SCEC Community Rheology Model (CRM)

The SCEC CRM provides a three-dimensional description of the ductile rheology of southern California’s lithosphere, based on constraints from seismic, geologic, and experimental rock deformation studies, and several rounds of Southern California Earthquake Center (SCEC) community input. The September 2020 release comprises two components: a three-dimensional geologic framework model (GFM) of southern California’s crust (i.e. major rock types and their distribution), and a set of synthetic aggregate ductile flow laws for each GFM rock type. We recommend using the SCEC CTM (Community Thermal Model, DOI https://doi.org/10.5281/zenodo.4010834) with the CRM to calculate effective viscosities.
