Sheldon Nevada Earthquake Sequence Datasets

This repository contains two movie visualizations and three datasets related to the Sheldon, NV (USA) earthquake sequence.

The movies are as follows:

1. movie_S1.mp4 provides a 3D visualization of the hypocentral locations of relocated Sheldon earthquakes, including the best fitting fault plane (a dipping normal fault) for the main part of the sequence. Events are color-coded by depth.
2. movie_S2.mp4 shows a time-evolution of relocated earthquakes, with events plotting in map view and color-coded by the distance from the fault plane shown in movie_S1.mp4. 

The datasets consist of two ASCII text files:

1. vzmodel.nonlinloc.txt is the velocity model used in the absolute and relative relocations (NonLinLoc format). 
2. growclust_relocations.txt is the relocated catalog for the sequence in GrowClust3D.jl output format.
3. sheldon_mt_compilation.csv is a compilation of moment tensor inversions for select larger earthquakes in the sequence. The columns are labeled in the file header:

• evid, datetime = NSL event id and centroid time
• lat, lon, depth = centroid position
• mw, mo: moment magnitude and moment in dyne-cm
• var: variance reduction of the fit
• mrr, mtt, mff, mrt, mrf, mtf: moment tensor components
• rlat, rlon, rdep: hypocentral position in relocated catalog
• reloc: indicator of a relocated event
• s1, d1, r1: strike, dip, rake of nodal plane 1
• s2, d2, d2: strike, dip, rake of nodal plane 2
