The 2002 U.S. Geological Survey (USGS) National Seismic Hazard Maps display earthquake ground motions for various probability levels across the United States and are applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. This update of the maps incorporates new findings on earthquake ground shaking, faults, seismicity, and geodesy. The resulting maps are derived from seismic hazard curves calculated on a grid of sites across the United States that describe the frequency of exceeding a set of ground motions.

The U.S. Geological Survey’s National Seismic Hazard Map Program publishes a number of products and tools designed to provide details of earthquake shaking hazards and help engineers meet modern seismic design provisions for the construction of buildings, bridges, highways, and utilities that are better able to withstand earthquakes, not only saving lives but also enabling critical activities to continue with less disruption.

The 2014 U.S. Geological Survey (USGS) National Seismic Hazard Maps display earthquake ground motions for various probability levels across the United States and are applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. The updated maps represent an assessment of the best available science in earthquake hazards and incorporate new findings on earthquake ground shaking, faults, seismicity, and geodesy. The USGS National Seismic Hazard Mapping Project developed these maps by incorporating information on potential earthquakes and associated ground shaking obtained from interaction in science and engineering workshops involving hundreds of participants,...

This data set represents probabilisitic seismic hazard curves and uniformhazard ground motion values calculated for a grid of points with a spacing of 0.2 degrees in latitude and longitude over the conterminous U.S. (CONUS) and Alaska (AK) using the 2023 National Seismic Hazard Model. CONUS The data sets includes (1) probabilistic seismic hazard curves (full and truncated) for two peak parameters, peak ground velocity (PGV) and peak ground acceleration (PGA), and pseudospectral accelerations at 21 oscillator periods between 0.01 and 10s, and (2) uniformhazard ground motion values for 2, 5, and 10% in 50 years probability of exceedance (PE) (corresponding to 2,475, 975, and 475year return periods, respectively)...

This data set represents multiple period response spectra (MPRS) results for 160 test sites for the conterminous U.S (CONUS) using the 2023 National Seismic Hazard Model. The data sets includes (1) probabilistic seismic hazard curves (full and truncated) for peak ground velocity (PGV), peak ground acceleration (PGA), and 21 spectra periods from 0.01 to 10 seconds spectra acceleration and (2) uniformhazard ground motion values for 2, 5, and 10% in 50 years probability of exceedance (PE) (corresponding to 2,475, 975, and 475year return periods, respectively) and 1% in 100 year PE (corresponding to a 10,000year return period) for each of the 160 test sites. Results are provided for VS30 = 1500, 1080, 760, 530, 365,...
