For designing buildings and other structures, the 2015 NEHRP Recommended Seismic Provisions and the 2016 ASCE/SEI 7 Standard contain maps of Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations and maps of Maximum Considered Earthquake Geometric Mean (MCEG) peak ground accelerations. The MCER ground motions are also in the 2017 ASCE/SEI 41 Standard and the 2018 and 2021 editions of the International Building Code. These MCER and MCEG ground motion maps are derived from USGS National Seismic Hazard Models via the gridded values of this data release. The data files in the "Child Items" below also underlie the corresponding USGS Seismic Design Web Services. See the "Related External Resources"...

This data release contains data sets associated with the 2023 50-State National Seismic Hazard Model Update. The 2023 50-State National Seimsic Hazard Model (NSHM) Update includes an update to the NSHMs for the conterminous U.S (CONUS, last updated in 2018), Alaska (AK, last updated in 2007), and Hawaii (last updated in 2001). Data sets include inputs like seismicity catalogs used as input to the smoothed seismicity model and updated induced seismicity zone polygons in the central and eastern U.S., as well as outputs like hazard curves and uniform-hazard ground motion values. Plots of selected data sets are also included. The data sets provided here are primarily for the 2023 CONUS NHSM and 2023 AK NSHM. Additional...

These data were calculated to estimate seismic hazard, risk, and design across South America using the latest data, models, and methods. The input data to the model, as well as the output data are available here. The input data includes a seismicity catalog, seismicity rate models, evaluation of earthquake sizes, fault geometry and rate parameters, and ground-motion models. Output data include hazard curves, and associated products, for peak ground acceleration and spectral accelerations at 0.2 and 1 s periods.
