    • Earthquake catalog (1568 to 2018) for the USGS National Seismic Hazard Model and Nuclear Regulatory Commission

    Metadata Updated: September 15, 2025

    The earthquake catalog was generated in August 2018 using the standard National Seismic Hazard Model methodology (Mueller, 2019) for the central and eastern United States. Pre-existing catalogs were merged, duplicate records were removed, the catalog was declustered, and induced earthquakes were removed. The final catalog contains 6802 records, M2.5–7.8, and extends from 1568 through July 2018.
