Datasets for the 2025 USGS National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands

This data release contains datasets associated with the 2025 U.S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The 2025 PRVI NSHM (Shumway and others, 2025), which is an update of the original 2003 PRVI NSHM (Mueller and others, 2003, 2010). Datasets include model inputs like seismicity catalogs, smoothed seismicity spatial probability density functions and rates, subduction interface fault geometry and geologic deformation model parameters, fault-system solutions for the earthquake rupture forecast (branch-averaged and epistemic), and outputs like mean hazard curves and uniform-hazard ground motion data, epistemic uncertainty data, and hazard and risk maps.
