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

This dataset contains full epistemic uncertainty results for the 2025 U.S. Geological Survey (USGS) National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands across both the Earthquake Rupture Forecast (ERF) and Ground Motion Characterization (GMC) model components. The datasets are separated into three epistemic categories: Full (ERF and GMC), ERF-only, and GMC-only. Hazard results are available for select periods and site conditions. The Full and GMC-only datasets include peak ground acceleration (PGA) and pseudo-spectra accelerations (SA) of 0.2, 1, and 5-s, calculated for Vs30=760 m/s and 260 m/s. The ERF-only datasets include PGA and SA of 1-s, calculated for Vs30=760 m/s. Hazard results were computed using OpenSHA (Field and others, 2003). Plots, as well as expanded descriptions, of these datasets are available at https://data.opensha.org/nshm25-prvi/.
