This page describes various file formats used by OpenSHA.
OpenSHA generally stores and reads geospatial data (including fault section data, regions, and gridded regions) in the GeoJSON format. View information on those file formats here.
The UCERF3 model introduced Fault System Rupture Sets and Solutions as data containers for earthquake rupture forecasts. We updated the legacy UCERF3 file formats to be more user friendly as part of the 2023 update to the U.S. National Seismic Hazard Model, replacing binary files with simpler ASCII, JSON, and GeoJSON representations.
