Description: 

The Southern California Earthquake Center (SCEC) has developed a collection of independent, but inter-related, open-source scientific software programs designed to support earthquake system science research. This SCEC software ecosystem includes the Unified Community Velocity Model (UCVM) to deliver several California crustal velocity models (CVM-S, CVM-H, UCVM), advanced Probabilistic Seismic Hazard Analysis (PSHA) methods (OpenSHA), broadband ground motion methods (Broadband Platform), deterministic wave propagation codes (AWP-ODC, Hercules), a physics-based PSHA platform (CyberShake) and an earthquake forecast testing center (CSEP). Over the last year, our SCEC research group has improved and simplified access to SCEC structural models by developing web-based query and visualization tools which provide access to SCEC fault, velocity, thermal and geological framework models, without requiring researchers to download and install software on their own systems. Epidemic [MOU1] Type Aftershocks Sequences (ETAS) short-term earthquake forecasting methods were implemented in the OpenSHA software, which produces earthquake forecasts as suites of future earthquake catalogs and SCEC’s Collaboratory for the Study of Earthquake Predictability (CSEP) project developed methods for evaluating short term forecasts expressed as stochastic events sets, by comparing the forecast event sets against observed earthquake catalogs, capabilities applied during the Ridgecrest earthquake sequence. SCEC’s Broadband Platform software has been extended to include additional new ground motion simulation methods, new validation events and support for multi-segment ruptures. The SCEC CyberShake software has been ported to the latest generation of supercomputers including OLCF Summit and TACC Frontera. As individual programs, and through the combined capabilities of multiple codes, the SCEC software ecosystem has enabled significant scientific and computing advances and important earthquake system science research.
