Earthquake geology inputs for the National Seismic Hazard Model (NSHM) 2023 (central and eastern United States), version 1.0

This Data Release contains three related databases for the Central and Eastern United States: 1) A fault sections database ("NSHM2023_FaultSections_CEUS_v1"), which depicts the geometry of faults capable of hosting independent earthquakes, 2) A fault zone polygon database ("NSHM2023_FaultPolygons_CEUS_v1"), which depicts the geometry of distributed fault zones capable of hosting repeated large magnitude events but a specific fault source remains unidentified, and 3) An earthquake geology site information database ("NSHM2023_EQGeoDB_CEUS_v1"), which contains fault slip-rate and earthquake recurrence constraints at points. These databases were prepared in anticipation of updates to the National Seismic Hazard Model (NSHM) 2023. Fault-specific geologic parameters for the NSHM have not been updated since the 2014 NSHM release, which included inputs from the 2012 Central and Eastern United States Seismic Source Characterization for nuclear facilities model. The databases in this Data Release include the states of Missouri, Illinois, Indiana, Arkansas, Tennessee, Kentucky, Oklahoma, South Carolina, Virginia, as well as southeast Canada (Quebec). These databases are provided as geospatial data (e.g., .SHP, .KML, .GEOJSON file formats) and tables (.CSV format).
