CGS Map Sheet 48: Fault-based seismic sources used in the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3)

Data show fault-based seismic sources used in the time-independent component of the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3), which provides authoritative estimates of the magnitude, location, and time-averaged frequency of potentially damaging earthquakes in California. Fault model slip rates are given in millimeters per year. The shapefile depicts the surface traces of modeled faults, which are simplified from the CGS – USGS Quaternary Fault and Fold database (https://earthquake.usgs.gov/hazards/qfaults/). For modeled blind fault seismic sources, the traces represent the map-view fault tip projection of the subsurface fault. For additional information regarding modeled faults in UCERF3 please refer to Appendix A of the UCERF3 report (https://pubs.usgs.gov/of/2013/1165/). For additional information about UCERF3 please see http://www.conservation.ca.gov/cgs/rghm/psha/Pages/sr_228.aspx for the full UCERF3 publication and supporting products.
