Updates to USGS National Seismic Hazard Model (NSHM) and Design Ground Motion Maps for 2020 NEHRP Recommended Provisions

摘要

This presentation summarizes the proposed updates to earthquake design ground motions for the 2020 edition of the NEHRP Recommended Seismic Provisions, expected to be incorporated into the ASCE 7-22 Standard. The implications of these updates on the values of design ground motions for example locations in both conterminous and non-conterminous U.S. cities are shown and discussed.
