Summary

The 2023 National Seismic Hazard Model for the conterminous United States considers the full catalog and several declustered catalogs in calculating earthquake rates and seismic hazard. These catalogs were declustered using the Reasenberg and nearest neighbor methods. All of these catalogs are included here and are described in more detail in the paper by Llenos and others (2023).
