Project Abstract
 The 2019 SCEC Community Rheology Model (CRM) workshop was held May 5, 2019 in Palm Springs, immediately before the annual leadership retreat. This focused, invitation-only workshop brought together deformation modelers who are likely to be users of the preliminary CRM; as well as representatives from the CXM and CRM focus groups,and SCEC IT. Morning presentations by the conveners described the preliminary (ductile) CRM. In the afternoon, two invited speakers described potential applications of the CRM to SCEC science. The meeting concluded with in-depth discussions of specific questions relating to design and implementation of the CRM (following up on a phone poll of modelers, conducted prior to the workshop).
Intellectual Merit The CRM and CTM contribute to several SCEC research objectives (for example, moving beyond elasticity as we improve deformation model-based estimates of fault slip rates and crustal stresses). The CTM and CRM are themselves key deliverables for SCEC5, and collaborative work on these consensus products is spurring scientific inquiry as assumptions are challenged, knowledge gaps are identified, and new questions arise.
Broader Impacts The SCEC community models (CXM's) provide the foundation for state-of-the-art science that is of clear societal significance (e.g. earthquake forecasts and rupture propagation - ground motion simulations). The CXM's are a freely available and accessible resource for scientists conducting research on southern California active tectonics and seismic hazard.
