   Are fault geometries a new geologic deformation model for the nshm23 update?

   • Here, we evaluate fault geometries and geologic fault slip rates for the western United States to construct a new geologic deformation model for the U.S. National Seismic Hazard Model 2023 update (NSHM23). In previous NSHM iterations, only faults with published geologic slip rates were included.

   Which source models were used to calculate seismic hazard?

   • Seismic hazard calculations were performed using the probabilistic seismic hazard analysis computer code, nshmp-haz (Powers et al., 2022) and the following source models: 2023 CONUS NSHM (Powers and Altekruse, 2022a), 2023 Alaska NSHM (Powers and Altekruse, 2023), and 2021 Hawaii NSHM (Powers and Altekruse, 2022b).

   Why are the changes in 2023 time-independent seismic hazard significant?

   • Changes in 2023 time-independent seismic hazard (both increases and decreases compared to previous NSHMs) are substantial because the new model considers more data and updated earthquake rupture forecasts and ground-motion components.

   Jan 2, 2024 · Western U.S. geologic deformation model for use in the U.S. National Seismic Hazard Model 2023, version 1.0. The U.S. National Seismic Hazard Model (NSHM) relies on deformation models to assign slip rates along active faults used in the earthquake rupture forecast. Here, we present the geologic deformation model results in tabular form.
