Preface to the Focus Section on Deformation Models for the U.S. National Seismic Hazard Model

The U.S. National Seismic Hazard Model (NSHM) defines the probability of scenarios of ground shaking from earthquakes and is used to guide building codes, insurance rate structures, and risk assessments. The NSHM will be updated in 2023 and will include the latest models of ground shaking, seismicity, and earthquake production rates. The latter is quantified with an earthquake rate model that depends on long‐term fault‐slip rates. Although these have been traditionally provided by geologically constrained slip rates, fault‐slip rates based on geodetic data and deformation models were first accommodated in the Third Uniform California Earthquake Rupture Forecast (UCERF3) in 2013...
