A key input for probabilistic seismic hazard analysis (PSHA) is geologic slip rate data. Here, we compile all geologic slip rates that are reportedly used in U.S. National Seismic Hazard Map (NSHM) releases from 1996, 2002, 2007, 2008, and 2014. Although a new NSHM was released in 2018, no changes were made in geologic slip rate data used. The geologic slip rates are collated from existing NSHM reports and documentation, and no new data are reported herein. The geologic slip rates are coupled with the fault geometries used in NSHM2014/2018 calculations. The data are presented spatially as a shapefile (SHP), in keyhole markup language (KML) and geoJSON. A readme file accompanies this dataset explaining details of...

The boundaries (polygons and their tables) of the zones of induced seismicity are provided as documentation for the 50-state update of the National Seismic Hazard Model (NSHM) of 2023. These zones are within the conterminous United States and have assigned durations to represent seismicity that is considered induced. Previous NSHMs also considered the role of induced seismicity (Petersen and others, 2018 and Petersen and others, 2017) which is a separate category from other anthropogenic sources considered in the seismicity catalogs used in the hazard models. For expanded explanations, see Llenos and others (2023) and the metadata which also contains documented references used in this study.

The 2023 National Seismic Hazard Model for the conterminous United States considers the full catalog and several declustered catalogs in calculating earthquake rates and seismic hazard. These catalogs were declustered using the Reasenberg and nearest neighbor methods. All of these catalogs are included here and are described in more detail in the paper by Llenos and others (2023).

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. We provide model outputs in multiple file formats, as well as the polygons used in analyses throughout the geologic deformation model process.The data presented herein are in support of the following interprative manuscript: Hatem, A.E., Reitman, N.G., Briggs, R.W., Gold, R.D., Thompson Jobe, J.A., Burgette, R.J., (2022) ­­­Western U.S. geologic deformation model for use in the U.S. National Seismic Hazard Model 2023, Seismological Research Letters.
