Session Time: 8:00 AM to 5:45 PM (local time)
The USGS National Seismic Hazard Models (NSHMs) are a bridge between best-available earthquake science and public policy. By the end of 2023, the National Seismic Hazard Model Project (NSHMP) will publish a 50-State NSHM, focusing on updates to the conterminous U.S., Alaska and Hawaii. The Puerto Rico and U.S. Virgin Islands NSHM will be updated by the end of 2025 (see 2025 Puerto Rico and the U.S. Virgin Islands National Seismic Hazard Model Update Technical Session), and updates to the Guam and Northern Mariana Islands and American Samoa and Neighboring South Pacific Islands NSHMs are tentatively scheduled to be completed by the end of 2026. Looking ahead to all future NSHM updates, we would like to consider new data, methods and models. For this session, we invite contributions on topics that will influence future seismic hazard models, including but not limited to: seismicity catalogs, declustering and smoothed seismicity models, geologic and geodetic deformation models, multi-fault ruptures, improved representation and quantification of epistemic uncertainty, new ground motion models (GMMs), including non-ergodic models, incorporation of physics-based (3D simulation) GMMs, basin effects, site response, directivity and time dependence. We also invite contributions on the use of NSHMs for scenario development, risk assessment for both buildings and infrastructure, and other applications of risk mitigation including those within the insurance industry. We are also interested in contributions that highlight potential impacts of hazard modeling uncertainties on downstream applications.
