This data set represents multi-period response spectra (MPRS) results for 36 Alaska test sites using the 2023 National Seismic Hazard Model for the state of Alaska. The data sets includes (1) probabilistic seismic hazard curves (full and truncated) for peak ground velocity (PGV), peak ground acceleration (PGA), and spectral accelerations at 21 spectral periods from 0.01 to 10 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) and 1% in 100 year PE (corresponding to a 10,000-year return period). Results are provided for Vs30s (time-averaged shear-wave velocity [VS] in the upper 30 m) of 1500, 1080, 760, 530, 365, 260, 185, and 150 m/s, representing the National Earthquake Hazards Reduction Program site conditions A, B, BC, C, CD, D, DE and E, 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.
