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...
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...
This dataset contains earthquake catalogs compiled for Alaska from U.S. Geolgical Survey (USGS) Advanced National Seismic System (ANSS) Comprehensive Earthquake Catalog (ComCat) (USGS, 2017) and Natural Resources Canada (NRCan) Canadian National Earthquake Database (NRCan, 1985) catalog searches and processed following the methods of Mueller (2019) and Llenos et al. (2024). Catalogs are deculstered using multiple methods and segregated into crustal, subduction interface, and subduction intraslab catalogs using Slab2 (Hayes, 2018).
