<p>Virtual Quake is a boundary element code that performs simulations of fault systems based on stress interactions between fault elements to understand long term statistical behavior. It uses field observations to define fault topology, long-term slip rates and frictional parameters. The faults are meshed into interacting elements and quasi-static elastic interactions are calculated between these elements. Stress is then applied to each element at geologically-observed rates until frictional parameters are exceeded. At this point an element will fail and transfer stress to the rest of the system. Under the correct conditions, transferred stress results in propagating ruptures throughout the system, i.e. a simulated earthquake. The design of Virtual Quake allows for fast execution so many thousands of events can be generated over very long simulated time periods. The result is a rich dataset from which to study the statistical properties of the rupturing fault system.</p>
<p>Additionally, many data visualization and analysis tools are provided in the PyVQ python script.</p>
<p>v3.0.0</p>
<p>This update adds a great deal of new functionality and stability:</p>
<ul>
<li>The rupture model has been overhauled for stability. Event slip matrix solutions have been removed in favor of a purely cellular automaton method.</li>
<li>Faults are now separate objects from sections. This allows ruptures to spread between sections belonging to the same larger fault, while allowing each section to have its properties defined independently.</li>
<li>Many new PyVQ plotting and filtering options have been added.</li>
<li>Several major and minor bugs have been fixed.</li>
</ul>

<p>We model deformation in the subduction channel (SC) and overriding plate as two-dimensional incompressible, Newtonian, isotropic, Stokes viscoelastic creeping flow under the influence of gravity in a Lagrangian finite element grid. SC flow in the trench-parallel direction is assumed to be small compared to flow along a plane normal to the trench axis. In this case, a 2D treatment can capture the predominant forces acting on the channel (i.e., the shear forces applied by the subducting plate and gravity-derived forces). Even if SC and upper plate materials may present short-scale (i.e., grain size) anisotropies in viscosity, we further assume, like many others, that there is no such anisotropy when averaged over longer scales. Since mantle and crustal motions can be considered as highly viscous creeping over geologic timescales, all inertial forces are negligible during creep. We thus use the Stokes approximation to fluid flow. Finally, rocks can typically recover part of their deformation once stress disappears, so we use a viscoelastic rather than a purely viscous rheology. For further simplicity in these initial models, we also assume a linear shear stress-shear rate relationship. A Newtonian rheology for the SC is consistent with the (micro)structural record of exhumed metamorphic rocks which indicates that deformation is localized in low-strength shear zones dominated by dissolution precipitation creep or fluid-assisted granular flow (Gerya and Stöckhert, 2002).</p>
<p>The model geometry is a several hundred-meter-thick SC at the interface between the upper plate and subducting slab. This geometry is inferred from imaging of SCs as ~100-1000-m-thick low-velocity layers (e.g., Sage et al., 2006). The lower model domain boundary is 100 km, while the eastern model domain boundary is 400 km. The Moho and upper crust-lower crust geometries are prescribed according to the Andean density model of Tassara et al. (2006).</p>
<p>Triangle C (Shewchuk, 1996) is used to generate ~10<sup>5</sup>-element unstructured two-dimensional Delaunay triangular meshes after each time step for two subdomains: the SC and the upper plate. A ~250 m horizontal resolution is achieved along the free surfaces. We follow deformation of the atmosphere-land and seafloor free surfaces using 10 kyr time steps, wherein deformation results from shear stresses imposed on the SC top by the subducting slab, by flow in the SC, by buoyancy forces originating from differences in density between SC and forearc materials, and by the weight of the water column in the case of the seafloor surface.</p>
<p>We use MILAMIN, a MATLAB-based finite element method mechanical solver (Dabrowski et al., 2008), modified to include the viscoelasticity terms. The incompressibility constraint is achieved through an iterative penalty method. A relatively small penalty factor k is used, guaranteeing a good condition number, and incompressibility of flow is achieved by Powell/Hestenes/Uzawa-type iterations (Dabrowski et al., 2008), that is also known as an Augmented Lagrangian formulation.</p>
In order to run the code, it is necessary to upload to the local environment the SuitSparse package functions, as well as the MUTILS 4.2 functions (both not included here).

<p><strong>What is the nature of flow in the mantle?</strong><br>
<strong>How fast do waves travel anywhere on Earth?</strong><br>
<strong>Where can radial anisotropy be robustly detected?</strong><br>
<strong>Can we reconcile a broad spectrum of seismic data? What are the benefits?</strong></p>
<p>We use normal-mode splitting functions in addition to surface-wave phase anomalies, body-wave travel times and long-period waveforms to construct a three-dimensional model of anisotropic shear-wave velocity in the Earth's mantle. This is the <strong>first tomographic study</strong> to exploit the sensitivity of mode-splitting data to constrain radial anisotropy in the Earth's mantle jointly with several other types of data. Our modeling approach inverts for mantle velocity and anisotropy as well as transition-zone discontinuity topographies, and incorporates new crustal corrections for the splitting functions that are consistent with the nonlinear corrections we employ for the waveforms. Our preferred anisotropic model, S362ANI+M, is an update to the earlier model S362ANI, which did not include normal-mode splitting functions in its derivation.</p>

<p>There are several significant differences that the user familiar with past versions of ConMan will find in the 3.0 version. First, we removed the clunky memory manager library (a set of routines wrapped around the c function malloc) and replaced them with FORTRAN 90's allocate and deallocate functions.<br>
This eliminates many of the compilation problems people experienced with the 2.0 version. <br>
Most of these routines were in files subroutines input and elminp. </p>
<p>As part of a general clean up, we replaced the separate input and elminp (both input subroutines) and created a new input subroutine. As part of this we removed the `element library' function (eglib.F and eg2.F) which was a structure originally designed for different formulations 2D Cartesian, 3D Cartesian, spherical axysymmetric, ...). Because these were never fully developed, it made on sense to retain the cumbersome structure. We also moved all out the subroutines associated with output, into new output subroutine. The user does not need to hunt through the time_driver subroutine to find out where the specific output subroutines are called. Thus, subroutines geoid, fluxke, masflx, print, output_rheol, print_compbm_data, and stress are all in subroutine output.</p>
<p>We also changed the names of many of the subroutines to take advantage of longer subroutine names allowed by modern FORTRAN. Thus f_tlhs has become form_temp_matrix, f_vres has become form_vel-ocity_rhs, f_vstf has become form_velocity_stiffness_matrix. Similarly, subroutine timdrv has become time_driver. As you look through the code there are examples where this could have been carried further.</p>
<p>Second, Picard iteration for the temperature equation is now a runtime option as opposed to a compiler option. This necessitated specifying both implicit and explicit subroutines for the temperature right hand side, form_temp_rhs_implicit and form_temp_rhs_explicit, a well as a form_temp_matrix for the implicit temperature matrix and form_temp_mass_matrix for the lumped mass matrix that has traditionally been used for the explicit version of the temperature solver.</p>
<p>Third, we added the EBA, TALA, and ALA formulations as described in [King et al, 2010]. The compressible formulation is described in Chapter 3 of the manual. This required a number of changes throughout the form_temperature and form_velocity subroutines. We provide a test suite that runs a subset of the problems from [King et al., 2010] that can be used to verify the installation version 3.0.0</p>
<p>Finally, we have added a cookbook of subduction wedge problems based on problems from the subduction zone benchmark paper [vanKeken et al., 2008] and one based on the compressible convection benchmark paper [King et al., 2010]. This required adding a new 'fault' subroutine and a subroutine to implement the Batchelor corner flow boundary conditions. These can be found in the subduct.src directory.</p>

<p>New Zealand Wide velocity model 2.3 has seismic velocity for New Zealand developed from local-earthquake tomography studies. It incorporates results from the southern South Island, published in Tectonics, using joint inversion of travel times and ambient noise derived group velocities (Eberhart-Phillips, et al., 2021, 2022). The results from that study have been interpolated and merged into the previous New Zealand Wide model 2.2 (zenodo.org/record/3779523)</p>
<p>The model is provided in tables, where the Spread Function (SF) shows the resolution, such that where SF<4, there is little information.</p>
<p>vlnzw2p3dnxyzltln.tbl.txt</p>
<p>There is also a simul format velocity file.</p>
<p>vlnzw2p3.mod.txt</p>
<p>And map plots with white lines denoting limits of adequate data, from the 2022 Southern South Island paper, and also for all New Zealand.</p>
<p>Figs_SouthernSI_Tect.pdf</p>
<p>mapvpvpvsnzw2p3.pdf</p>
<p>Velocities any point within the 3D gridded models are defined by linearly interpolating between nodes.</p>
<p>The models use Transverse Mercator coordinate transformation with a central meridian= 173, and counterclockwise rotation of 140. Earth-flattening transformation is used for velocity during ray-tracing. The depths are relative to sea-level. Density has been included in the velocity table, by using an empirical relationship (Gardner et al., 1974; Hill, 1978).</p>

<p>The world's most devastating local and ocean-wide tsunamis are generated by subduction zone earthquakes, but the mechanisms for powerful seafloor uplift and tsunami generation during seismic rupture propagation remain poorly understood. In particular, great earthquakes near the trench can generate outsize tsunamis that rival those produced by giant trench-breaking ruptures. Solving this conundrum is key to better assessing seismic and tsunami hazards at subduction zones. Here, we inspect high-resolution bathymetry, seismic reflection profiles, and tsunami-earthquake rupture models at global subduction zones to identify the structural control on tsunami excitation by coseismic seafloor uplift. We find that tsunami run-ups of trench-breaking ruptures correlate with the width of the outer wedge of the frontal accretionary prism, which consists of active imbricate or conjugate faults above the shallow megathrust. The prevalence of high-angle faults in the outer wedge provides the mechanism for more efficient seafloor uplift and thus tsunami wave excitation than coseismic slip on the shallow decollement. We calibrate a power-law relationship with outer-wedge width and seismic moment to estimate the maximum tsunami run-up along major subduction zones. The tsunami excitation potential is among the highest at the northern Sumatra (Indonesia), Hikurangi (New Zealand), and western Makran (Iran) accretionary margins, and the lowest at the Costa Rica and Valdivia (Chile) erosive margins. The structural control of tsunami excitation is important to characterize the rupture style and tsunami magnitude of future seismicity at subduction zones, offering crucial information for seismic and tsunami hazard preparedness and rapid run-up assessment during the early-warning stage, especially at well-identified seismic gaps.</p>

<p>The Geodynamic World Builder (GWB) is an open source code library intended to set up initial conditions for computational geodynamic models and/or visualize complex 3d teconic setting, in both Cartesian and Spherical geometries. The inputs for the JSON-style parameter file are not mathematical, but rather a structured nested list describing tectonic features, e.g. a continental, an oceanic or a subducting plate. Each of these tectonic features can be assigned a specific temperature profile (e.g. plate model) or composition label (e.g. uniform). For each point in space, the GWB can return the composition and/or temperature. It is written in C++, but can be used in almost any language through its C, Python and Fortran wrappers. Various examples of 2D and 3D subduction settings are presented.</p>

<p><strong>The Resource Geology Seismic Processing System for Java (JRG)</strong> is a basic seismic reflection processing package with great graphics, record animation, 3-d and crooked-line capabilities, SEG-Y, SAC, and sound file I/O, and a friendly GUI that runs on any desktop or laptop. It lacks muting or migrations. More information at <a href="https://louie.pub">Louie.pub</a></p>
<p><strong>Senior Undergrad Applied Geophysics Class Lab Exercises </strong>using JRG function as basic user tutorials and reference manuals for the software, available on Google Drive <a href="https://drive.google.com/open?id=1-Ix1_t0_MHKfssS5xQCgmcbzV6cemaN_">here</a>. The refraction and refraction microtremor labs refer to commercial software. You can use other methods, or contact <a href="mailto:johnnlouie@gmail.com?subject=Inquiry%20on%20commercial%20software%20and%20JRG">johnnlouie@gmail.com</a> about the commercial software. There are two versions of each lab. The older full versions were meant to be demonstrated during the lab periods and then worked on by individual students for one or two weeks. The newer short versions are cut back to be worked on and answered by student teams entirely within the 2.75 hour lab period.</p>
<p><strong>To run the Viewmat app and start JRG</strong>, double-click on the jrg500.jar or jrg2G.jar file. Use the jrg2G.jar version, unless your computer has less than 4 Gb RAM. The source code is zipped into the jrg-src.jar file.</p>
<p>JRG is partly an adaptation of the UNIX command-line-based Resource Geology Seismic Processing System. See https://Louie.pub for more information. That site also links to Applied Geophysics, Geophysical Series and Filtering, and Seismic Imaging class lab exercises that use JRG.</p>

<p>We are pleased to announce the release of ASPECT 2.2.0. ASPECT is the Advanced Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from</p>
<pre><code> https://aspect.geodynamics.org/
</code></pre>
<p>and the release is available from</p>

</code></pre>
<p>This release includes the following significant changes:</p>
<ul>
<li>
<p>New: There is a new matrix-free Stokes solver which uses geometric multigrid. This method is significantly faster than the default algebraic multigrid preconditioner and uses less memory. Free surface and melt transport are not yet implemented. (Thomas C. Clevenger, Timo Heister)</p>
</li>
<li>
<p>New: There is now a new approximation for the compressible convection models that is called 'projected density field'. (Rene Gassmoeller, Juliane Dannberg, Timo Heister, Wolfgang Bangerth)</p>

<p>Incompatibility: The option to use PETSc for linear algebra has been removed until further notice. (Timo Heister)</p>
</li>
<li>
<p>New: If the user has the libdap libraries installed then input data can be pulled from the server instead of a local file. (Kodi Neumiller, Sarah Stamps, Emmanuel Njinju, James Gallagher)</p>

</li>
<li>
<p>New: There is now a general class <code>MaterialModel::Utilities::PhaseFunction</code> that can be used to model phase transitions using a smooth phase function. (Rene Gassmoeller, John Naliboff, Haoyuan Li)</p>
</li>
<li>
<p>New: ASPECT now includes a thermodynamically self-consistent compressible material model, that implements the Modified Tait equation of state that is described in Holland and Powell, 2011. (Bob Myhill)</p>
</li>
<li>
<p>New: The material models can now outsource the computation of the viscosity into a separate rheology model. (Rene Gassmoeller)</p>

<p>We are pleased to announce the release of ASPECT 2.4.0. ASPECT is the Advanced<br>
Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such<br>
as adaptive mesh refinement, multigrid solvers, and a modular software design to<br>
provide a fast, flexible, and extensible mantle convection solver. ASPECT is<br>
available from</p>
<pre><code> https://aspect.geodynamics.org/
</code></pre>
<p>and the release is available from</p>
<pre><code> https://geodynamics.org/resources/aspect
</code></pre>
<p>and</p>
<pre><code> https://github.com/geodynamics/aspect/releases/tag/v2.4.0
</code></pre>
<p>Among others this release includes the following significant changes:</p>
<ul>
<li>
<p>New: ASPECT now requires deal.II 9.3.0 or newer, and cmake 3.1.0 or newer.<br>
(Timo Heister)</p>
</li>
<li>
<p>New: The matrix-free GMG Stokes solver now works for problems with<br>
free-surface boundaries and elasticity.<br>
(Jiaqi Zhang, Anne Glerum, Timo Heister, John Naliboff)</p>

Newton solver.<br>
(Timo Heister, Menno Fraters, Jiaqi Zhang)</p>
</li>
<li>
<p>New: Visualization postprocessors now record the physical units of the<br>
quantity they compute, and this information is also output into visualization<br>
files with a sufficiently new version of deal.II.<br>
(Wolfgang Bangerth)</p>
</li>
<li>
<p>New: Where possible, when using large data tables as input (e.g., for initial<br>
conditions specified as tables), these data are now stored only once on each<br>
node in memory areas that is accessible by all MPI processes on that node.<br>
(Wolfgang Bangerth)</p>
</li>
<li>
<p>New: There is now a new material model for melting in the lowermost mantle.<br>
It can be used to reproduce the results of Dannberg et al. (2021).<br>

</li>
<li>
<p>New: There is now a 'static' option for the temperature field that is set-up<br>
similarly to the 'static' option for compositional fields. This allows the<br>
temperature field to be constant over time so you can still advect and build<br>
up elastic stresses.<br>

<li>
<p>Changed: The initial composition model called 'ascii data' can now read in 3d<br>
ascii datasets into a 2d model and slice the dataset in a user controlled<br>
plane. This allows it to make high-resolution 2d models of problems that use<br>
observational data (such as seismic tomography models).<br>
(Juliane Dannberg, Rene Gassmoeller)</p>
</li>
<li>

<pre><code> https://geodynamics.org/resources/aspect
</code></pre>
<p>and</p>
<pre><code> https://github.com/geodynamics/aspect/releases/tag/v2.5.0
</code></pre>
<p>Among others this release includes the following significant changes:</p>
<ul>
<li>
<p>ASPECT now includes version 0.5.0 of the Geodynamic World Builder. (Menno Fraters and other contributors)</p>
</li>
<li>
<p>ASPECT's manual has been converted from LaTeX to Markdown to be hosted as a website at <a href="https://aspect-documentation.readthedocs.io">https://aspect-documentation.readthedocs.io</a>. (Chris Mills, Mack Gregory, Timo Heister, Wolfgang Bangerth, Rene Gassmoeller, and many others)</p>
</li>
<li>
<p>New: ASPECT now requires deal.II 9.4 or newer. (Rene Gassmoeller, Timo Heister)</p>
</li>
<li>
<p>ASPECT now supports a DebugRelease build type that creates a debug build and a release build of ASPECT at the same time. It can be enabled by setting the CMake option CMAKE_BUILD_TYPE to DebugRelease or by typing "make debugrelease". (Timo Heister)</p>
</li>
<li>
<p>ASPECT now has a CMake option ASPECT_INSTALL_EXAMPLES that allows building and install all cookbooks and benchmarks. ASPECT now additionally installs the data/ directory. Both changes are helpful for installations that are used for teaching and tutorials. (Rene Gassmoeller)</p>
</li>
<li>
<p>Changed: ASPECT now releases the memory used for storing initial conditions and the Geodynamic World Builder after model initialization unless an owning pointer to these objects is kept. This reduces the memory footprint for models initialized from large data files. (Wolfgang Bangerth)</p>
</li>
<li>
<p>Added: Various helper functions to distinguish phase transitions for different compositions and compositional fields of different types. (Bob Myhill)</p>
</li>
<li>
<p>Added: The 'adiabatic' initial temperature plugin can now use a spatially variable top boundary layer thickness read from a data file or specified as a function in the input file. Additionally, the boundary layer temperature can now also be computed following the plate cooling model instead of the half-space cooling model. (Daniel Douglas, John Naliboff, Juliane Dannberg, Rene Gassmoeller)</p>
</li>
<li>
<p>New: ASPECT now supports tangential velocity boundary conditions with GMG for more geometries, such as 2D and 3D chunks. (Timo Heister, Haoyuan Li, Jiaqi Zhang)</p>
</li>
<li>
<p>New: Phase transitions can now be deactivated outside a given temperature range specified by upper and lower temperature limits for each phase transition. This allows implementing complex phase diagrams with transitions that intersect in pressure-temperature space. (Haoyuan Li)</p>
</li>
<li>
<p>New: There is now a postprocessor that outputs the total volume of the computational domain. This can be helpful for models using mesh deformation. (Anne Glerum)</p>
</li>
<li>
<p>New: Added a particle property 'grain size' that tracks grain size evolution on particles using the 'grain size' material model. (Juliane Dannberg, Rene Gassmoeller)</p>
</li>
<li>
<p>Fixed: Many bugs, see link below for a complete list. (Many authors. Thank you!).</p>

<p>Virtual Quake is a boundary element code that performs simulations of fault systems based on stress interactions between fault elements to understand long term statistical behavior. It uses field observations to define fault topology, long-term slip rates and frictional parameters. The faults are meshed into interacting elements and quasi-static elastic interactions are calculated between these elements. Stress is then applied to each element at geologically-observed rates until frictional parameters are exceeded. At this point an element will fail and transfer stress to the rest of the system. Under the correct conditions, transferred stress results in propagating ruptures throughout the system, i.e. a simulated earthquake. The design of Virtual Quake allows for fast execution so many thousands of events can be generated over very long simulated time periods. The result is a rich dataset from which to study the statistical properties of the rupturing fault system.</p>
<p>Additionally, many data visualization and analysis tools are provided in the PyVQ python script.</p>
<p>v3.1.1</p>
<ul>
<li>A mesher bug has been fixed that was causing incorrect interpolation of fault properties between trace points.</li>
</ul>
<p>v3.1.0</p>
<ul>
<li>Improved mesher to better handle faults with a curved trace and shallow dip.</li>
</ul>
<p>v3.0.0</p>
<p>This update adds a great deal of new functionality and stability:</p>
<ul>
<li>The rupture model has been overhauled for stability. Event slip matrix solutions have been removed in favor of a purely cellular automaton method.</li>
<li>Faults are now separate objects from sections. This allows ruptures to spread between sections belonging to the same larger fault, while allowing each section to have its properties defined independently.</li>
<li>Many new PyVQ plotting and filtering options have been added.</li>
<li>Several major and minor bugs have been fixed.</li>
</ul>

The 3D Reference Earth Model (REM3D) Consortium
2022-12-13
<p>Reconciliation of techniques, models and data has emerged as a frontier area for deep Earth exploration. Past results have proven indispensable for assessing earthquake hazard, characterizing plate tectonics, elucidating material properties under extreme conditions, imaging interior structure, and as a general reference in other fields. We present advancements on a three-dimensional reference Earth model (REM3D) that captures the consensus view of heterogeneity in the mantle.</p>
<p>Progress in modeling the Earth’s interior is driven by diverse data, ranging from astronomic-geodetic constraints to full seismic waveforms and derivative measurements of body waves (~ 1 – 20s), surface waves (~ 20 – 300s) and normal modes (~ 250 – 3000s). Reconciliation of data involves retrieving the missing metadata, archiving in scalable storage formats, documenting outliers indicative of the limitations in some techniques, and quantifying summary reference data with uncertainties. Building on our recent work on reference surface-wave dispersion datasets, arrival times of primary, diffracted, and reflected phases from the transition-zone and deeper discontinuities are reconciled for a body-wave reference dataset. This procedure involves revised techniques and archival formats for the processing of frequency-dependent arrival times. A revised dataset of normal-mode eigenfrequencies, quality factors and splitting is reconciled with updated uncertainties based on inter-catalog consistencies.</p>
<p>Full-spectrum tomography uses these diverse observations to constrain physical properties – seismic velocity, anisotropy, density, attenuation and the topography of discontinuities – in variable spatial resolution. This technique is expanded to include long-wavelength geoid as an additional constraint on density variations. All geoscience workflows typically involve querying data or models in order to make inferences. Analysis and Visualization toolkit for plaNetary Inferences (AVNI) is a web-based software environment powered by Python that facilitates these computational workflows. AVNI tools are web-based so that the shared resources are accessed by authenticated users through Application Programming Interfaces (APIs), without the overhead of storing data, compiling and running intensive codes.</p>

<p><strong>SELEN: a program for solving the "Sea Level Equation"</strong></p>
<p>The open source program SELEN solves numerically the so-called "Sea Level Equation" (SLE) for a spherical, layered, non-rotating Earth with Maxwell viscoelastic rheology. The SLE is an integral equation that was introduced in the 70s to model the sea level variations in response to the melting of late Pleistocene ice sheets, but it can also be employed to present-day melting of continental ice-sheets. SELEN can compute vertical and horizontal surface displacements, gravity variations and sea level changes on a global and regional scale. SELEN (acronym of SEa Level EquatioN solver) is particularly oriented to scientists at their first approach to the glacial isostatic adjustment (GIA) problem and, according to our experience, it can be successfully used in teaching. The current release (2.9) considerably improves the previous version of the code in terms of computational efficiency, portability and versatility.</p>

<p>The Geodynamic World Builder (GWB) is an open source code library intended to set up initial conditions for computational geodynamic models and/or visualize complex 3d teconic setting, in both Cartesian and Spherical geometries. The inputs for the JSON-style parameter file are not mathematical, but rather a structured nested list describing tectonic features, e.g. a continental, an oceanic or a subducting plate. Each of these tectonic features can be assigned a specific temperature profile (e.g. plate model) or composition label (e.g. uniform). For each point in space, the GWB can return the composition and/or temperature. It is written in C++, but can be used in almost any language through its C, Python and Fortran wrappers. Various examples of 2D and 3D subduction settings are presented.</p>

<p>This repository accompanies the paper</p>
<p> </p>
<p>```</p>
<p>Dannberg, J., Gassmoeller, R., Thallner, D., LaCombe, F., Sprain, C.: Changes in core-mantle boundary heat flux patterns throughout the supercontinent cycle.</p>
<p>```</p>
<p> </p>
<p>This repository contains instructions for how to obtain the boundary conditions from GPlates, ASPECT code, data and model setups, and scripts for converting the ASPECT model output to spherical harmonics so it can be used in geodynamic simulations. To reproduce the workflow follow the steps:</p>
<p> </p>
<p>- To create the velocity boundary conditions for the ASPECT models, download the plate reconstruction from 'Merdith, A.S., Williams, S.E., Collins, A.S., Tetley, M.G., Mulder, J.A., Blades, M.L., Young, A., Armistead, S.E., Cannon, J., Zahirovic, S. and Müller, R.D., 2021. Extending full-plate tectonic models into deep time: Linking the Neoproterozoic and the Phanerozoic. Earth-Science Reviews, 214, p.103477', which can be found here:</p>
<p> </p>
<p>https://doi.org/10.5281/zenodo.4485738</p>
<p> </p>
<p>To create the 'lat_lon_velocity' files, take the following steps in GPlates:</p>
<p> </p>
<p>1. Load all of the files from the Merdith et al, 2021 plate reconstruction into a Feature Collection which can be saved as a project (the project for our visualization is 'project.gproj').</p>
<p>2. Establish the output grid (ours is lat_lon_velocity_domain_91_181): Features -> Generate Velocity Domain Points -> Latitude Longitude -> Number of latitudinal grid intervals=91, Number of longitudinal grid intervals=181, number of nodes=16652.</p>
<p>3. To output the point velocities we used for the models: Reconstruction -> Export -> Add Export -> Velocities, GPML(*.gpml), velocity_%nMa</p>
<p>- The data files we created following this workflow are part of this data publication and can be found in the `lat_lon_velocity` folder.</p>
<p> </p>
<p>- The global spherical convection models of the publication were created using two different ASPECT configurations:</p>
<p> </p>
<p>Models `thermal`, `thermochemical`, and `p-T-dependent` were run using:</p>
<p> </p>
<p>```</p>
<p>-----------------------------------------------------------------------------</p>
<p>-- This is ASPECT, the Advanced Solver for Problems in Earth's ConvecTion.</p>
<p>-- . version 2.4.0-pre (limit_shear_heating, 4f45a72fe)</p>
<p>-- . using deal.II 9.4.0-pre (3d869ba6cd1fd462624e09dc232e34ed17880701)</p>
<p>-- . with 64 bit indices and vectorization level 2 (256 bits)</p>
<p>-- . using Trilinos 12.18.1</p>
<p>-- . using p4est 2.3.2</p>
<p>-----------------------------------------------------------------------------</p>
<p>```</p>
<p> </p>
<p>Models `strong basalt` and `weak ppv` were run using:</p>
<p> </p>
<p>```</p>
<p>-----------------------------------------------------------------------------</p>
<p>-- This is ASPECT, the Advanced Solver for Problems in Earth's ConvecTion.</p>
<p>-- . version 2.5.0-pre (limit_shear_heating_and_ppv, a4812c95a)</p>
<p>-- . using deal.II 9.4.2</p>
<p>-- . with 64 bit indices and vectorization level 3 (512 bits)</p>
<p>-- . using Trilinos 13.2.0</p>
<p>-- . using p4est 2.3.2</p>
<p>-----------------------------------------------------------------------------</p>
<p>```</p>
<p> </p>
<p>- The two modified ASPECT versions are included in this data package. The repository including full</p>
<p>version history is until further notice available as branch `limit_shear_heating` and branch `limit_shear_heating_and_ppv`</p>
<p>in the repository `https://github.com/jdannberg/aspect.git`.</p>
<p> </p>
<p>- Running these models also requires plugins that are located in the `shared_libs` folder in this repository and that need to be compiled. Navigate into this directory and follow the steps:</p>
<p> </p>
<p>1. `cmake -D Aspect_DIR=PATH_TO_ASPECT` (replace `PATH_TO_ASPECT` with the directory where you compiled ASPECT).</p>
<p>2. `make`</p>
<p>- Now the models in this repository can be started. You should start them from the `input_files` directory so that all paths are set correctly and you can start them with the ASPECT executable in your build folder.</p>
<p> </p>
<p>- The files in `aspect_input_files` correspond to the models presented in the paper following the same naming scheme.</p>
<p> </p>
<p>- To convert the ASPECT heat flux output to spherical harmonics we used the script `analyze_heatflux_mpi_gmt.py` in `SPH_scripts`,</p>
<p>which requires modification to point to the correct ASPECT statistics file and the correct output directory.</p>
<p> </p>
<p>- The final heat flux output is included in this data package in the `heat_flux` folder, which includes archives of the processed heat flux output in 1 Myr time intervals with 0 being the start of the model run and the highest timestep number representing the present day state.</p>

<p>Manuscript in revision: <em>Earth and Space Science, </em>December 20, 2021</p>
<p><em>Abstract</em></p>
<p>To date, approximately 20% of the ocean floor has been surveyed by ships at a spatial resolution of 400 m or better. The remaining 80% has depth predicted from satellite altimeter-derived gravity measurements at a relatively low resolution. There are many remote ocean areas in the southern hemisphere that will not be completely mapped at 400 m resolution during this decade. This study is focused on the development of synthetic bathymetry to fill the gaps. There are two types of seafloor features that are not typically well resolved by satellite gravity: abyssal hills and small seamounts (< 2.5 km tall). We generate synthetic realizations of abyssal hills by combining the measured statistical properties of mapped abyssal hills with regional geology including fossil spreading rate/orientation, rms height from satellite gravity, and sediment thickness. With recent improvements in accuracy and resolution, It is now possible to detect all seamounts taller than about 800 m in satellite-derived gravity and their location can be determined to an accuracy of better than 1 km. However, the width of the gravity anomaly is much greater than the actual width of the seamount so the seamount predicted from gravity will underestimate the true seamount height and overestimate its base dimension. In this study we use the amplitude of the vertical gravity gradient (VGG) to estimate the mass of the seamount and then use their characteristic shape, based on well surveyed seamounts, to replace the smooth predicted seamount with a seamount having a more realistic shape. </p>
<p>SYNBATH_V1.2 September 20, 2021</p>
<p>This version of SYNBATH has abyssal hills as described below. Superimposed on that are 30,000 gaussian seamounts with sigma to height ratios of 2.4. The heights were determined by fitting a uncompensated model VGG for a seamount of a particular height to the observed VGG in a 33 by 33 km area using a density of 2800 kg m^-3. Any seamount taller than 2600 m or less than 700 m was not used.</p>
<p>SYNBATH_V1.1 July 6, 2021</p>
<p>A refined version of the SYNBAPS with better blending</p>
<p>SYNBATH_V1.0 July 1, 2021</p>
<p>This is the first version of SYNthetic BATHymetry (SYNBATH) that is a merge of the latest SRTM15 global bathymetry/topography grid and synthetic abyssal hill fabric based on an anisotropic power spectral model published by Goff and others [2010, 2020]. The synthetic abyssal fabric fills the voids in the real bathymetry coverage that used to be filled by predicted depth.</p>
<p>These are global grids with 86400 columns and 43200 rows in NETCDF format.</p>

<p><span> The program 'simul2023' provided in this zenodo site is a flexible program for simultaneous inversion of travel-time data for 3-D velocity and hypocenters. We have used it extensively since the 1980s, and it has evolved over that time with modifications to the original code of Thurber (1983). Eberhart-Phillips (1990) developed the Simulps code to use P and S travel- times to solve for Vp and Vs. From Simulps, other groups have evolved simul versions with useful modifications (Haslinger and Kissling, 2001), which are not included in simul2023. All S travel-time ray-paths are calculated using the 3-D Vs structure in the Eberhart-Phillips (1990) code and all subsequent modified codes such as Eberhart-Phillips and Reyners (1997, 2012) and Eberhart-Phillips and Fry (2017). </span></p>
<p><span> <a name="_Hlk155877169"></a> Simul2023 is an update of simul2017.<span> </span>This has improvements to shallow derivatives for shorter period group velocity, earthquake residual weighting and earth-flattening transformation velocity partial derivatives. An additional hypocentre output file includes <span>many error parameters, which were being computed but not retained, and assigns quality codes (Eberhart-Phillips and Reyners, 2023).<span> </span>Hypocenter depths may be fixed on relocation, if desired.<span> </span>For consistency with simul2000, control parameters kspr and ieft may be adjusted.</span></span></p>
<p><span><br> The Simul codes parameterize velocity on a 3-D grid of nodes with velocity linearly interpolated between nodes, allowing flexible gridding through linking of nodes (Thurber and Eberhart-Phillips, 1999). The solution is obtained by damped least squares, with no other smoothing applied, to obtain a model that has few artefacts and stays close to the initial model where there is low resolution. For typical earthquake travel-time data, the Vs model is poorly constrained relative to the Vp model, less representative of crustal structure and difficult to use for interpreting Vp/Vs (Eberhart-Phillips, 1989). Thus, as described by Eberhart-Phillips and Reyners (1997), it is preferable to solve for Vp and Vp/Vs, when using local earthquake travel-time data. This parameterization is retained for group velocity, with the Herrmann (2013) Vp kernels related to Vp model inversion parameters and Vs kernels related to partial derivatives of Vp and Vp/Vs model parameters (Eberhart-Phillips and Fry, 2017; Eberhart-Phillips et al., 2022).<br> <br> Rietbrock (2001) implemented Q inversion in simul, using t* observations which describe path attenuation from spectral decay. This has been extremely useful in many settings, since Q has ability to characterize many features more distinctly than velocity (eg: Eberhart-Phillips et al., 2020; Eberhart-Phillips, 2016). It can be used for Qp or Qs, and does not need to solve for hypocenters. The code was extended for joint teleseimic and local inversion for velocity or Q (Eberhart-Phillips and Fry, 2018).<br> <br> The simul2023 code is a complete fortran code. The beginning of the code has descriptions of input parameters. An old users manual for an early version may be of some use (Evans et al., 1994). Our work has taken the approach of adding new features, without eliminating previous options. There are examples in the examples directory. For further knowledge of input formats, the input subroutines can be reviewed. The include file has parameters related to array size and the user should consider adjusting these. There should be no need to edit the fortran code. A notable input parameter is 'nitmax', specifying the number of iterations, relocation only (0), or create synthetic data (-1). The coordinate system model cartesian coordinates and distances are computed with Transverse Mercator conversion, and earth-flattening transformation is used. The coordinates are defined at the beginning of input file 2 (stations), and older options of short-distance conversion or NZMG49 are allowed. The model 0-km depth equates to a present sea-level datum, the z= -1 km depth grid is 1 km above sea-level, and velocity is linearly interpolated between gridded nodes. Travel-time ray-tracing includes station elevations. There are several options of travel-time data format, selected by input parameter kttfor, and used in subroutine input4.</span></p>
<p><span> There are descriptions of the input and output files at the beginning of the fortran program.<span> </span>That beginning portion is also provided here as a separate file: simul2023.f_notes.txt.</span></p>

<p>THERMOD is Windows-based software that performs numerical simulations of heat conduction and advection in 1d and 2d systems. It consists of three programs (THERMOD8, THERMODSUBDUCT, and PREPARRAYS) and a user’s manual. THERMOD8 performs simulations of 1d and 2d systems; 2d systems may involve faults of specified geometry and displacement velocity. THERMODSUBDUCT performs 2d numerical simulations of subduction zones and includes features not included in THERMOD8 (mantle corner flow, corner flow truncation, and frictional heating). Users operate the programs through graphical user interfaces to set up and run models, modify saved models, and export results. </p>
Development of the software was funded by National Science Foundation grants EAR-9317378 and
EAR-9805076 (THERMOD8) and EAR-1929520 (THERMODSUBDUCT AND PREPARRAYS)

<p><strong>Is there a chemically distinct reservoir in the Earth?</strong><br><strong>Do superplumes overly denser-than-average material?</strong><br><strong>Can we detect these anomalies with seismic data?</strong><br><strong>Can we evaluate statistical significance of the features in tomography?</strong></p><p>This study presents the <strong>strongest evidence</strong> to date (ca. 2015) of <strong>large-scale thermo-chemical heterogeneities in the lowermost mantle</strong> using the full spectrum of seismic data. A large data set of surface-wave phase anomalies, body-wave travel times, normal-mode splitting functions and long-period waveforms is used to investigate the scaling between shear velocity, density and compressional velocity in the Earth's mantle (ϱ=dln ρ/dln vS, ν=dln vS/dln vP). Our preferred joint model consists of denser-than-average anomalies (∼1% peak-to-peak) at the base of the mantle roughly coincident with the low-velocity superplumes. The relative variation of shear velocity, density and compressional velocity in our study disfavors a purely thermal contribution to heterogeneity in the lowermost mantle, with implications for the long-term stability and evolution of superplumes.</p><p><strong>Note on Odd Degree Structure:</strong></p><p>Since the self-coupled normal-mode splitting observations constrain only even-degree density variations, all inversions strongly disfavored even-degree vS-ρ correlation (R2 ~ –0.46 to –0.25) in the lowermost mantle, which also disfavors a purely thermal contribution to heterogeneity in this region. However, the starting assumptions on positive vS-ρ correlation persisted in the remaining regions and for odd degree variations. In viscosity inversions with the geoid, opposing sign of the correlation of the longest wavelength even-versus odd-degree structure maps into a region of reduced viscosity in the lower mantle (Rudolph et al., 2020, doi:10.1029/2020gc009335). While important for such dynamical implications, <strong>odd-degree density variations in the lowermost mantle are poorly constrained in this study and should not be interpreted</strong>. We therefore used even-degree variations up to degree 6 for our inferences on thermo-chemical variations in the lowermost mantle (Figure 14), and provide those values in the files below.</p><p><strong>Feedback/Questions?</strong> Please contact Raj Moulik (<a href="https://rajmoulik.com">rajmoulik.com</a>) at <a href="mailto:moulik@caa.columbia.edu?subject=Query%20from%20Zenodo">moulik@caa.columbia.edu</a> </p><p><strong>Reference:</strong></p><p><i>Please cite the following work if you use this data or software.</i></p><ul><li>Moulik, P. & Ekström, G., 2016.

Refer cij in equation 3. This is our preferred global model of anisotropic elastic parameters and density. Density variations are allowed to deviate from a constant scaling with shear-velocity variations in the lowermost mantle, which is required to fit the longest-period normal modes (e.g. 0S2). Radial anisotropy is confined to the uppermost mantle (that is, since the anisotropy is parameterized with only the four uppermost splines, it becomes very small below a depth of 250 km, and vanishes at 410 km). This is an updated version of S362ANI+M (Moulik and Ekström, 2014) which did not solve independently for density and compressional-wave velocity variations and imposed a constant scaling throughout the mantle instead (ϱ=0, ν=1/0.55).</li><li><a href="https://zenodo.org/api/files/9aa99409-20ae-495e-b5a3-288fd57ecaeb/STW105"><strong>STW105</strong></a> - reference model used in ME16.

<p>Version 3.0.0 includes major changes to the underlying finite-element formulation and implementation in order to support a more flexible specification of the governing equations and higher order basis functions. These changes affect how simulations are defined. Parameter files for previous versions will need to be updated; the changes are too complex for a simple translation table. Some features present in v2.2.2, such as spontaneous rupture and finite strain, have not yet been implemented in the new formulation.</p>
<p>Features</p>
<ul>
<li>Multiphysics
<ul>
<li>Elasticity for linear isotropic materials and linear Maxwell, generalized Maxwell, and power law viscoelastic models</li>
<li>Incompressible elasticity for linear isotropic materials</li>
<li>Prescribed slip for quasistatic and dynamic simulations</li>
</ul>
</li>
<li>Higher order basis functions Allow user to select order of basis functions independent of the mesh (which defines the geometry). This permits higher resolution for a given mesh.</li>

<p>This is a bug fix release with no new features or changes to the user interface.</p>
<ul>
<li>Fixed duplicate integration of fault terms if a fault had one material on one side and multiple materials on the other side.</li>
<li>Fixed bugs related to running in parallel.
<ul>
<li>Creating constraints on buried fault edges failed for some mesh distribution cases.</li>
<li>Green's function problems did not manage fault impulses on multiple processes.</li>
<li>Creating a point mesh for <code>OutputSolnPoints</code> failed when running in parallel.</li>
<li>PetscSF inconsistencies generated errors at various times when running in parallel.</li>
</ul>
</li>
<li>Update to PETSc 3.18.0.</li>
</ul>
<p><strong>Note</strong>: We now use PETSc routines to write the HDF5 files. As a result, there is one change to the layout: <code>topology/cells</code> is now <code>viz/topology/cells</code>.<br>
The corresponding Xdmf files reflect this change.</p>
<p><strong>Known issues</strong></p>
<p>The rate of convergence of the linear solver for large models (millions of cells) with large fault surfaces (most of the domain) is slow when running in parallel. We are working on finding better preconditioner settings.</p>

<p><em><strong>21-May-2022</strong> There are updated Vp and Vp/Vs models 2.3, which incorporate the results from the Southern South Island region, at zenodo.org/record/6568301 </em></p>
<p>The Qs and Qp New Zealand Wide models 2.3 incorporate the results from the Kaikoura region using aftershocks, published in Geophysical Journal International (Eberhart-Phillips, et al. 2021).</p>
<p>The results from that study have been interpolated and merged into the previous New Zealand Wide model 2.2 (zenodo.org/record/3779523).</p>
<p> </p>
<p>The models are provided in tables, where the Spread Function (SF) shows the resolution, such that where SF<4, there is little information.</p>
<p>Qpnzw2p3xyzltln.tbl.txt</p>

<p> </p>
<p>Q at any point within the 3D gridded models is defined by linearly interpolating between nodes.</p>
<p>The models use Transverse Mercator coordinate transformation with a central meridian= 173, and counterclockwise rotation of 140. Earth-flattening transformation is used for velocity during ray-tracing. The depths are relative to sea-level.</p>

<p>Virtual Quake is a boundary element code that performs simulations of fault systems based on stress interactions between fault elements to understand long term statistical behavior. It uses field observations to define fault topology, long-term slip rates and frictional parameters. The faults are meshed into interacting elements and quasi-static elastic interactions are calculated between these elements. Stress is then applied to each element at geologically-observed rates until frictional parameters are exceeded. At this point an element will fail and transfer stress to the rest of the system. Under the correct conditions, transferred stress results in propagating ruptures throughout the system, i.e. a simulated earthquake. The design of Virtual Quake allows for fast execution so many thousands of events can be generated over very long simulated time periods. The result is a rich dataset from which to study the statistical properties of the rupturing fault system.</p>
<p>Additionally, many data visualization and analysis tools are provided in the PyVQ python script.</p>
<p>v3.1.0</p>
<ul>
<li>Improved mesher to better handle faults with a curved trace and shallow dip.</li>
</ul>
<p>v3.0.0</p>
<p>This update adds a great deal of new functionality and stability:</p>
<ul>
<li>The rupture model has been overhauled for stability. Event slip matrix solutions have been removed in favor of a purely cellular automaton method.</li>
<li>Faults are now separate objects from sections. This allows ruptures to spread between sections belonging to the same larger fault, while allowing each section to have its properties defined independently.</li>
<li>Many new PyVQ plotting and filtering options have been added.</li>
<li>Several major and minor bugs have been fixed.</li>

<p> The program 'simul2017' provided in this zenodo site is a flexible program for simultaneous inversion of travel-time data for 3-D velocity and hypocenters. We have used it extensively since the 1980s, and it has evolved over that time with modifications to the original code of Thurber (1983). Eberhart-Phillips (1990) developed the Simulps code to use P and S travel- times to solve for Vp and Vs. From Simulps, other groups have evolved simul versions with useful modifications (Haslinger and Kissling, 2001), which are not included in simul2017. All S travel-time ray-paths are calculated using the 3-D Vs structure in the Eberhart-Phillips (1990) code and all subsequent modified codes such as Eberhart-Phillips and Reyners (1997, 2012) and Eberhart-Phillips and Fry (2017). <br> <br> These parameterize velocity on a 3-D grid of nodes with velocity linearly interpolated between nodes, allowing flexible gridding through linking of nodes (Thurber and Eberhart-Phillips, 1999). The solution is obtained by damped least squares, with no other smoothing applied, to obtain a model that has few artefacts and stays close to the initial model where there is low resolution. For typical earthquake travel-time data, the Vs model is poorly constrained relative to the Vp model, less representative of crustal structure and difficult to use for interpreting Vp/Vs (Eberhart-Phillips, 1989). Thus, as described by Eberhart-Phillips and Reyners (1997), it is preferable to solve for Vp and Vp/Vs, when using local earthquake travel-time data. This parameterization is retained for group velocity, with the Herrmann (2013) Vp kernels related to Vp model inversion parameters and Vs kernels related to partial derivatives of Vp and Vp/Vs model parameters (Eberhart-Phillips and Fry, 2017; Eberhart-Phillips et al., 2022).<br> <br> Rietbrock (2001) implemented Q inversion in simul, using t* observations which describe path attenuation from spectral decay. This has been extremely useful in many settings, since Q has ability to characterize many features more distinctly than velocity (eg: Eberhart-Phillips et al., 2020; Eberhart-Phillips, 2016). It can be used for Qp or Qs, and does not need to solve for hypocenters. The code was extended for joint teleseimic and local inversion for velocity or Q (Eberhart-Phillips and Fry, 2018).<br> <br> The simul2017 code is a complete fortran code. The beginning of the code has descriptions of input parameters. An old users manual for an early version may be of some use (Evans et al., 1994). Our work has taken the approach of adding new features, without eliminating previous options. There are examples in the examples directory. For further knowledge of input formats, the input subroutines can be reviewed. The include file has parameters related to array size and the user should consider adjusting these. There should be no need to edit the fortran code. A notable input parameter is 'nitmax', specifying the number of iterations, relocation only (0), or create synthetic data (-1). The coordinate system model cartesian coordinates and distances are computed with Transverse Mercator conversion, and earth-flattening transformation is used. The coordinates are defined at the beginning of input file 2 (stations), and older options of short-distance conversion or NZMG49 are allowed. The model 0-km depth equates to a present sea-level datum, the z= -1 km depth grid is 1 km above sea-level, and velocity is linearly interpolated between gridded nodes. Travel-time ray-tracing includes station elevations. There are several options of travel-time data format, selected by input parameter kttfor, and used in subroutine input4.</p>

<p>This release fixes a number of bugs that could cause crashes at output time.</p>
<p>1.) Several output-quantity codes were double-booked. This could cause issues with quantity codes in the following ranges: 1900--2000 (kinetic energy equation codes) 1400--1600 (thermal energy equation codes) 1600--1800 (magnetic energy equation codes)</p>
<p>The output quantity tables have been adjust accordingly.</p>
<p>2.) Logical errors affecting outputs involving v' dot grad v' have been corrected.</p>
<p>3.) The configure script now accepts the --with-custom and -devel flags (run ./configure --help for details)</p>

</li>
<li>
<p>Fixed two bugs in output of solution at points that sometimes happened in parallel simulations. The errors include:</p>
<ul>
<li>
<p>The order of the station names does not match the order of the points. The point data is written in parallel by process order, so the points for process 0 are written first, then those for process 1, etc. This often results in reordering of the points. The station names were written in the original order.</p>
</li>
<li>
<p>The output values for some points are incorrect. The wrong cells were being used in the interpolation.</p>
</li>
</ul>
</li>
<li>
<p>Updated PETSc to v3.7.5.</p>

<p><strong>21-May-2022</strong> There are updated Vp and Vp/Vs models 2.3, which incorporate the results from the Southern South Island region, at zenodo.org/record/6568301</p>
<p><strong>13-July-2021</strong> There are updated Qp and Qs models 2.3, which incorporate the results from the Kaikoura region, at zenodo.org/record/5098356</p>
<p> </p>
<p>New Zealand Wide model 2.2 has a seismic velocity model for New Zealand developed from local-earthquake tomography studies. It is updated, from nzwide2.1 (zenodo.org/record/1043558), to incorporate results from the western North Island (Eberhart-Phillips and Fry, 2017) and the southern Hikurangi Cook Strait region (Henrys, et al., 2020). The Cook Strait results were interpolated and merged into the NZwide model and then additional inversion including some Kaikoura aftershocks was carried out to assure the model is appropriate for regional use.</p>
<p> </p>
<p>The Qp model 2.2 is updated from Qpnzw1 (Eberhart-Phillips et al., 2015), to incorporate results from the eastern North Island (Eberhart-Phillips et al., 2017) and southern South Island (Eberhart-Phillips et al., 2018).</p>
<p> </p>
<p>There has not been New Zealand wide Qs coverage until this year, and the NZwide 2.2 Qs model is the first complete Qs model. We are using the version name <strong>nzw2.2</strong> to denote all the seismic property models since many applications require all the parameters. The Qs model 2.2 incorporates results from the eastern North Island (Eberhart-Phillips et al., 2017), western North Island and mantle wedge (Eberhart-Phillips et al., 2020), northern South Island (Eberhart-Phillips et al., 2014), and southern South Island (Eberhart-Phillips et al., 2018).</p>
<p> </p>
<p>The models are provided in tables, where the Spread Function (SF) shows the resolution, such that where SF<4, there is little information.</p>

<p>Velocity and Q at any point within the 3D gridded models are defined by linearly interpolating between nodes.</p>
<p>The models use Transverse Mercator coordinate transformation with a central meridian= 173, and counterclockwise rotation of 140. Earth-flattening transformation is used for velocity during ray-tracing. The depths are relative to sea-level. Density has been included in the velocity table, by using an empirical relationship (Gardner et al., 1974; Hill, 1978).</p>

<p>We are pleased to announce the release of ASPECT 2.0.1. ASPECT is the Advanced Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from</p>

<pre><code> https://github.com/geodynamics/aspect/releases/tag/v2.0.1
</code></pre>
<p>This release is a bugfix release for 2.0.0 and includes the following fixes:</p>
<ul>
<li>Fixed: The 'compositional heating' heating plugin had a parameter 'Use compositional field for heat production averaging' that was used inconsistently with its description. Its first entry did not correspond to the background field, but to the first compositional field, and the last value was ignored. This is fixed now, the first entry is used for the background field, and all following values determine whether to include the corresponding compositional fields.</li>
<li>Fixed: The 'depth dependent' material model did not properly initialize the material model it uses as a base model. This caused crashes if the base model requires an initialization (such as the 'steinberger' material model). This is fixed now by properly initializing the base model.</li>
<li>Fixed: The advection assembler for DG elements was not thread-safe, which led to wrong results or crashes if a discontinuous temperature or composition discretization was combined with multithreading.</li>
<li>Disabled: The particle functionality was not tested when combined with a free surface boundary, and this combination is currently not supported. This limitation is now made clear by failing for such setups with a descriptive error message.</li>

<li><strong>How fast do surface waves travel globally after any earthquake?</strong></li>
<li><strong>Do we get the same information from various measurement techniques?</strong></li>
<li><strong>Which features in the Earth are robust and can be resolved by a reference model?</strong></li>
</ul>
<p>Reference data with uncertainties are useful for improving existing measurement techniques, validating models of interior structure, calculating teleseismic data corrections in local or multiscale investigations and developing a 3-D reference Earth model. This study was done in collaboration with 18 scientists from 16 institutions in 7 countries who actively participated in the <a href="http://rem3d.org">REM3D</a> project. The project assimilated, archived, reconciled and modeled big (>200 million measurements) and diverse <a href="https://globalseismology.princeton.edu/data/surface-waves">surface-wave datasets</a> for global subsurface structure.</p>
<p>The reference data set summarizes measurements of dispersion of fundamental-mode surface waves and up to six overtone branches from 44,871 earthquakes recorded on 12,222 globally distributed seismographic stations. Dispersion curves are specified at a set of reference periods between 25 and 250 s to determine propagation-phase anomalies with respect to a reference Earth model. Empirically determined observational uncertainties (1 sigma) for each wave type, branch number and period can be found in Table 3. </p>
<p><strong>Summary:</strong></p>
<p><strong>[I]</strong> <strong>Reconciled large and diverse catalogues</strong> of Love-wave (49.65 million) and Rayleigh-wave dispersion (177.66 million) from eight groups worldwide.<br>
<strong>[II]</strong> Retrieved missing station and earthquake <strong>metadata</strong> in several legacy compilations and codified <strong>scalable formats</strong> to facilitate reproducibility, easy storage and fast I/O on HPC systems.<br>
<strong>[III]</strong> <strong>Systematic discrepancies </strong>between raw phase anomalies can be attributed to discrepant theoretical approximations, reference Earth models and processing schemes.<br>
<strong>[IV]</strong> <strong>Phase-velocity variations</strong> yielded by the inversion of the summary data set are <strong>highly correlated</strong> (R ≥ 0.8) with those from the quality-controlled contributing data sets, especially for long-wavelength variations (up to degree ∼25) in fundamental-mode dispersion (50–100 s).<br>
<strong>[IV]</strong> <strong>Only 2ζ azimuthal variations</strong> in phase velocity of <strong>fundamental-mode Rayleigh waves</strong> are <strong>required</strong>; maps of 2ζ azimuthal variations are highly consistent between catalogues ( R = 0.6–0.8).</p>

<p>Summary (reference) data between pairs of 2562 evenly-spaced knot points with an average spacing of 4.33◦. These files store the data in the RSDF HDF5 container format. These can be read using standard HDF5 modules (e.g. h5py) or using <a href="http://avni.globalseismology.org/">AVNI</a>. For example, to read the reference data for fundamental mode R1 waves at 100s into a Pandas Dataframe containing data (df['data']) and a dictionary with the metadata (df['metadata']), and thereafter write contents to an ASCII text file, enter the following in Python:</p>
<ul>
<li><em>from avni.data.SW import readSWhdf5,writeSWascii</em></li>
<li><em>df=readSWhdf5(query='0/100.0/R1/REM3D',hdffile='Summary.SW.Rayl.data.h5',datatype='summary')</em></li>
<li><em>writeSWascii(df,'test.txt')</em></li>
</ul>
<p><strong>ASCII (text) Format</strong></p>
<p>These files contain the same reference data as the HDF5 files above but in gzipped ASCII files. The files are named according to the overtone branch, wave type and period as <em>Summary.$overtone.$wave.$period.REM3D.gz</em> Table A1 from the paper describes the various columns in the surface-wave RSDF ASCII format files.</p>

<p>In the geosciences as in other scientific areas, computation has become a core component of research, complementing field observation, laboratory analysis, experiment, and theory. Computational tools for data analysis, mapping, visualization, modeling, and simulation are essential for all aspects of the scientific workflow. Specialized scientific software is often developed by geoscientists for their own use, and this effort represents a distinctive intellectual contribution that can be on par with data collection and publications. Thus it is important to be able to properly attribute this effort, both to assign credit to the software authors and contributors, and to establish the provenance of software, promote its reuse, and support efforts to ensure reproducibility of scientific results.<em> </em>Drawing on a geoscience community that focuses on developing and disseminating scientific software, we assess the current practices of software attribution.</p>
<p>The recent citation practices of the Computational Infrastructure for Geodynamics (CIG), geodynamics.org, community were assessed by examining its publication list from 2010-2015 [Article List.csv]. In addition, for all CIG held codes, we examine the citation requests by developers in their user's manual [Citation Request.CSV].</p>
<p>Please see README.rtf for data descriptions</p>
This project is supported by the U.S. National Science Foundation award number SMA-1448633. CIG is supported by the National Science Foundation award NSF-0949446.

<p>The Geodynamic World Builder (GWB) is an open source code library intended to set up initial conditions for computational geodynamic models and/or visualize complex 3d teconic setting, in both Cartesian and Spherical geometries. The inputs for the JSON-style parameter file are not mathematical, but rather a structured nested list describing tectonic features, e.g. a continental, an oceanic or a subducting plate. Each of these tectonic features can be assigned a specific temperature profile (e.g. plate model) or composition label (e.g. uniform). For each point in space, the GWB can return the composition and/or temperature. It is written in C++, but can be used in almost any language through its C and Fortran wrappers. Various examples of 2D and 3D subduction settings are presented.</p>

<p>THERMOD is Windows-based software that performs numerical simulations of heat conduction and advection in 1d and 2d systems. It consists of three programs (THERMOD8, THERMODSUBDUCT, and PREPARRAYS) and a user’s manual. THERMOD8 performs simulations of 1d and 2d systems; 2d systems may involve faults of specified geometry and displacement velocity. THERMODSUBDUCT performs 2d numerical simulations of subduction zones and includes features not included in THERMOD8 (mantle corner flow, corner flow truncation, and frictional heating). Users operate the programs through graphical user interfaces to set up and run models, modify saved models, and export results. </p>
Development of the software was funded by National Science Foundation grants EAR-9317378 and
EAR-9805076 (THERMOD8) and EAR-1929520 (THERMODSUBDUCT AND PREPARRAYS)

<p>This repository accompanies the paper</p>
<p> </p>
<p>```</p>
<p>Dannberg, J., Gassmoeller, R., Thallner, D., LaCombe, F., Sprain, C.: Changes in core-mantle boundary heat flux patterns throughout the supercontinent cycle.</p>
<p>```</p>
<p> </p>
<p>This repository contains instructions for how to obtain the boundary conditions from GPlates, ASPECT code, data and model setups, and scripts for converting the ASPECT model output to spherical harmonics so it can be used in geodynamic simulations. To reproduce the workflow follow the steps:</p>
<p> </p>
<p>- To create the velocity boundary conditions for the ASPECT models, download the plate reconstruction from 'Merdith, A.S., Williams, S.E., Collins, A.S., Tetley, M.G., Mulder, J.A., Blades, M.L., Young, A., Armistead, S.E., Cannon, J., Zahirovic, S. and Müller, R.D., 2021. Extending full-plate tectonic models into deep time: Linking the Neoproterozoic and the Phanerozoic. Earth-Science Reviews, 214, p.103477', which can be found here:</p>
<p> </p>
<p>https://doi.org/10.5281/zenodo.4485738</p>
<p> </p>
<p>To create the 'lat_lon_velocity' files, take the following steps in GPlates:</p>
<p> </p>
<p>1. Load all of the files from the Merdith et al, 2021 plate reconstruction into a Feature Collection which can be saved as a project (the project for our visualization is 'project.gproj').</p>
<p>2. Establish the output grid (ours is lat_lon_velocity_domain_91_181): Features -> Generate Velocity Domain Points -> Latitude Longitude -> Number of latitudinal grid intervals=91, Number of longitudinal grid intervals=181, number of nodes=16652.</p>
<p>3. To output the point velocities we used for the models: Reconstruction -> Export -> Add Export -> Velocities, GPML(*.gpml), velocity_%nMa</p>
<p>- The data files we created following this workflow are part of this data publication and can be found in the `lat_lon_velocity` folder.</p>
<p> </p>
<p>- The global spherical convection models of the publication were created using two different ASPECT configurations:</p>
<p> </p>
<p>Models `thermal`, `thermochemical`, and `p-T-dependent` were run using:</p>
<p> </p>
<p>```</p>
<p>-----------------------------------------------------------------------------</p>
<p>-- This is ASPECT, the Advanced Solver for Problems in Earth's ConvecTion.</p>
<p>-- . version 2.4.0-pre (limit_shear_heating, 4f45a72fe)</p>
<p>-- . using deal.II 9.4.0-pre (3d869ba6cd1fd462624e09dc232e34ed17880701)</p>
<p>-- . with 64 bit indices and vectorization level 2 (256 bits)</p>
<p>-- . using Trilinos 12.18.1</p>
<p>-- . using p4est 2.3.2</p>
<p>-----------------------------------------------------------------------------</p>
<p>```</p>
<p> </p>
<p>Models `strong basalt` and `weak ppv` were run using:</p>
<p> </p>
<p>```</p>
<p>-----------------------------------------------------------------------------</p>
<p>-- This is ASPECT, the Advanced Solver for Problems in Earth's ConvecTion.</p>
<p>-- . version 2.5.0-pre (limit_shear_heating_and_ppv, a4812c95a)</p>
<p>-- . using deal.II 9.4.2</p>
<p>-- . with 64 bit indices and vectorization level 3 (512 bits)</p>
<p>-- . using Trilinos 13.2.0</p>
<p>-- . using p4est 2.3.2</p>
<p>-----------------------------------------------------------------------------</p>
<p>```</p>
<p> </p>
<p>- The two modified ASPECT versions are included in this data package. The repository including full</p>
<p>version history is until further notice available as branch `limit_shear_heating` and branch `limit_shear_heating_and_ppv`</p>
<p>in the repository `https://github.com/jdannberg/aspect.git`.</p>
<p> </p>
<p>- Running these models also requires plugins that are located in the `shared_libs` folder in this repository and that need to be compiled. Navigate into this directory and follow the steps:</p>
<p> </p>
<p>1. `cmake -D Aspect_DIR=PATH_TO_ASPECT` (replace `PATH_TO_ASPECT` with the directory where you compiled ASPECT).</p>
<p>2. `make`</p>
<p>- Now the models in this repository can be started. You should start them from the `input_files` directory so that all paths are set correctly and you can start them with the ASPECT executable in your build folder.</p>
<p> </p>
<p>- The files in `aspect_input_files` correspond to the models presented in the paper following the same naming scheme.</p>
<p> </p>
<p>- To convert the ASPECT heat flux output to spherical harmonics we used the script `analyze_heatflux_mpi_gmt.py` in `SPH_scripts`,</p>
<p>which requires modification to point to the correct ASPECT statistics file and the correct output directory.</p>
<p> </p>
<p>- The final heat flux output is included in this data package in the `heat_flux` folder, which includes archives of the processed heat flux output in 1 Myr time intervals with 0 being the start of the model run and the highest timestep number representing the present day state.</p>

<p>We are pleased to announce the release of ASPECT 2.3.0. ASPECT is the Advanced Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid solvers, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from</p>
<pre><code> https://aspect.geodynamics.org/
</code></pre>
<p>and the release is available from</p>
<pre><code> https://geodynamics.org/cig/software/aspect/
</code></pre>
<p>and</p>
<pre><code> https://github.com/geodynamics/aspect/releases/tag/v2.3.0
</code></pre>
<p>Among others this release includes the following significant changes:</p>
<ul>
<li>
<p>New: ASPECT now requires deal.II 9.2.0 or newer. (Timo Heister)</p>
</li>
<li>
<p>New: ASPECT has a new, reproducible logo. (Rene Gassmoeller, Juliane Dannberg)</p>
</li>
<li>
<p>New: Mesh deformation now also works in combination with particles. Instead of the end of the timestep, particles are now advected before solving the compositional field advection equations. In iterative advection schemes, the particle location is restored before each iteration. (Anne Glerum, Rene Gassmoeller, Robert Citron)</p>
</li>
<li>
<p>New: ASPECT now supports the creation of visualization postprocessors that only output data on the surface of a model. An example is the "surface stress" visualization postprocessor. (Wolfgang Bangerth)</p>
</li>
<li>
<p>New: A new class TimeStepping::Manager to control time stepping with a plugin architecture has been added. The architecture allows to repeat time steps if the time step length changes significantly. (Timo Heister)</p>
</li>
<li>
<p>New: A mesh refinement plugin that allows to set regions of minimum and maximum refinement level between isosurfaces of solution variables. (Menno Fraters and Haoyuan Li)</p>
</li>
<li>
<p>New: There is a new nullspace removal option 'net surface rotation', which removes the net rotation of the surface. (Rene Gassmoeller)</p>
</li>
<li>
<p>New: Particle advection can now be used in combination with the repetition of timesteps. Before each repetition the particles are restored to their previous position. (Anne Glerum)</p>
</li>
<li>
<p>New: There is a new property in the depth average postprocessor that averages the mass of a compositional field (rather than its volume). (Juliane Dannberg)</p>
</li>
<li>
<p>New: The Drucker Prager rheology module now has an option to include a plastic damper, which acts to stabilize the plasticity formulation. At sufficient resolutions for a given plastic damper viscosity, the plastic shear band characteristics will be resolution independent. (John Naliboff and Cedric Thieulot)</p>
</li>
<li>
<p>New: ASPECT can now compute viscosity values depending on the values of phase functions for an arbitrary number of phases. (Haoyuan Li, 2020/08/06)</p>
</li>
<li>
<p>New: Added calculation for temperature-dependent strain healing in the strain dependent rheology module. (Erin Heilman)</p>
</li>
<li>
<p>New: Added new rheology module, which computes the temperature dependent Frank Kamenetskii viscosity approximation. (Erin Heilman)</p>
</li>
<li>
<p>New: ASPECT now includes a CompositeViscoPlastic rheology module. This rheology is an isostress composite of diffusion, dislocation and Peierls creep rheologies and optionally includes a damped Drucker-Prager plastic element. The rheology module for Peierls creep includes a formulation to compute the exact Peierls viscosity, using an internal Newton-Raphson iterative scheme. (Bob Myhill, John Naliboff and Magali Billen)</p>
</li>
<li>
<p>New: There is a new visualization postprocessor 'principal stress', which outputs the principal stress values and directions at every point in the model. (Rene Gassmoeller)</p>
</li>
<li>
<p>New: Added the functionality to compute averages in user defined depth layers (e.g. lithosphere, asthenosphere, transition zone, lower mantle) to the depth average postprocessor and the lateral averaging plugin. (Rene Gassmoeller)</p>
</li>
<li>
<p>New: The 'spherical shell' geometry model now supports periodic boundary conditions in polar angle direction for a 2D quarter shell (90 degree opening angle). (Kiran Chotalia, Timo Heister, Rene Gassmoeller)</p>
</li>
<li>
<p>New: A new particle interpolator based on quadratic least squares has been added. (Mack Gregory, Gerry Puckett)</p>
</li>
<li>
<p>New: There is now a mesh deformation plugin "diffusion" that can be used to diffuse surface topography in box geometry models. (Anne Glerum)</p>
</li>
<li>
<p>Bug fixes to: Steinberger and Calderwood viscosity profile, particle generation, viscous strain weakening, incompressible equation of state, pressure sign convention, Neumann heat flow boundaries with the Newton solver, viscosity on the adiabat for extended Boussinesq approximation models, and many more. (many authors)</p>
</li>

<p><strong>StagLab</strong> (<a href="http://www.fabiocrameri.ch/software">www.fabiocrameri.ch/software</a>) is a software package that incorporates an extensive suite of <strong><em>fully-automated Geodynamic diagnostics</em></strong> and, crucially, applies <em><strong>state-of-the-art, scientific visualisation</strong></em> to produce publication-ready figures and movies, all in a blink of an eye, all fully reproducible. Indeed, StagLab is the first fully scientific visualisation software as it uses <em>only</em> perceptually uniform colour maps (from <a href="http://www.fabiocrameri.ch/visualisation">www.fabiocrameri.ch/visualisation</a>) to prevent significant visual errors that would otherwise distort the underlying data and mislead the reader. StagLab, a simple, flexible, efficient and reliable tool, is written in MatLab and adjustable for use with Geodynamic mantle-convection codes.</p>
The development of StagLab is supported by the Research Council of Norway through its Centers of Excellence funding scheme, Project Number 223272.
