Project Abstract
 A set of existing seismic velocity models for different parts of California have been assembled and converted into multiple formats. Five of these models have been integrated into the SCEC CEM (UCVM) archive with assistance from SCEC staff. Workflows for additional format conversions have been developed, and work on disseminating those workflows will continue after this project ends.
SCEC Community Models Used Community Velocity Model (CVM)
Usage Description Seismic velocity models were added to the SCEC UCVM and are accessible through the SCEC Community Velocity Model Explorer tool.
Intellectual Merit Having ready access to more seismic velocity models facilitates efforts at wavefield simulation and provides models that can be used for model merging work.
Broader Impacts The use of wavefield simulations with high-quality seismic velocity models contributes to earthquake hazard information, and our work makes such models readily available to the community.
Project Participants Mei-Hui Xu, SCEC, assisted with integrating seismic velocity models into the UCVM.
