2025 Puerto Rico and the U.S. Virgin Islands National Seismic Hazard Model Update
The National Seismic Hazard Model Project (NSHMP) will publish a new Puerto Rico and U.S. Virgin Islands (PRVI) NSHM in 2025. The last update was in 2003, therefore the new update will include over 20-years of new science and engineering data, models and methods. The NSHMP has requested the scientific community bring our attention to published earthquake source and ground motion models (GMMs) that could be included in this update by December 31, 2022. Planned updates for the 2025 PRVI NSHM include new seismicity models, based on an improved Puerto Rico Seismic Network seismicity catalog, updated geologic and geodetic deformation models, NGA-West2 and NGA-Subduction GMMs, site response models and uncertainty estimates.

NSHMs are community- and consensus-based models that are constantly aiming to incorporate the latest data, models and methods available to evaluate and validate hazard assessments as we undertake this updating process. This session will outline the plan and timeline for the 2025 PRVI NSHM Update, feature new source and ground motion data and models that will be considered in the 2025 model, as well as showcase current work being performed in the region that may impact future PRVI NSHM updates. We invite abstracts on new sources and GMMs, risk assessments, building code applications and other policy uses. We also invite abstracts from end users on applications and needs of NSHMs in end user products.
