Creep rate models for California faults in the 2023 US National Seismic Hazard Model

Widespread surface creep is observed across a number of active faults included in the US National Seismic Hazard Model. In northern California, creep occurs on the central section of the San Andreas Fault, along the Hayward and Calaveras faults through the San Francisco Bay Area, and to the north coast region along the Maacama and Bartlett Springs faults. In southern California, creep is observed across the Coachella segment of the San Andreas Fault, through the Brawley Seismic Zone, and along the Imperial and Superstition Hills Faults. Seismic hazard assessments for California have accounted for creep using various data and methods, including the most recent Unified California Earthquake Rupture Forecast, version 3 (UCERF3) in 2013. The updated surface creep rate compilation consists of variety of data types including alignment arrays, offset cultural markers, creepmeters, InSAR, and GPS data. We compile a total of 497 surface creep rate measurements, 400 of which are new and 97 of which appear in the UCERF3 compilation.
