Forthcoming Updates of the USGS NSHMs: Hawaii, Conterminous U.S. and Alaska [Poster]
The U.S. Geological Survey (USGS) National Seismic Hazard Models (NSHMs) are the bridge between best-available earthquake science and public policy. In the next few years, the National Seismic Hazard Model Project (NSHMP) will complete three model updates: Hawaii (2020), the conterminous U.S. (COUS, 2023) and Alaska (2024?). The Hawaii seismic hazard model was last updated in 1998. The NSHMP is currently in the process of updating this model and held a public workshop in September 2019 to present early findings and solicit feedback from the scientific community. The current status of the model will be presented in this session, as well as preliminary hazard results. The COUS model was last updated in 2018 and includes NGA-East ground motion models (GMMs) in the central and eastern U.S. and basin amplifications in the western U.S. (WUS). The next model update for the COUS will be in 2023 with a focus on updating the WUS source model and subduction zone GMMs. The deadline for publications that the USGS may consider for this update is December 2020. We have also begun to plan for the Alaska NSHM, last updated in 2007.
For this session, we invite contributions relevant to the 2023 COUS and Alaska NSHM updates including, but not limited to: Atlantic and Gulf Coast and other alternative site amplification models, new fault models (WUS and Alaska), UCERF3 update/simplification, NGA-Subduction GMMs, physics-based (3D simulation) ground motion model validation and implementation, non-ergodic aleatory uncertainty, basin models, new geodetic data and inversions, M-area scaling relations and the Alaska megathrust geometry and recurrence.
