This dataset represents probabilistic seismic hazard curves and uniform-hazard ground motion values calculated for a grid of points with a spacing of 0.2 degrees in latitude and longitude for the state of Alaska using the 2023 National Seismic Hazard Model (NSHM) for the state of Alaska. The dataset includes (1) probabilistic seismic hazard curves (full and truncated) for peak ground acceleration (PGA), and spectral acceleration for 0.2, 1.0, 2.0, and 5.0 seconds and (2) uniform-hazard ground motion values for 2, 5, and 10% in 50 years probability of exceedance (PE) (corresponding to 2,475, 975, and 475 year return periods, respectively) for each grid point. Results are provided for site classes BC and D, which correspond with Vs30s (time-averaged shear-wave velocity [VS] in the upper 30 m) of 760 and 260 m/s, respectively. Two different sets of hazard curves are available, full (curves.csv) and truncated (curves-truncated.csv). The full gridded hazard curves data include ground motions at long return periods, whereas the truncated curves only span return periods of 10,000 years (annual frequency of exceedance of 1.0E-04) and less. The National Seismic Hazard Models are not intended to provide ground motions at return periods longer than 10,000 years.
