Mar 9, 2022 · What are the USGS National Seismic Hazard Maps? The National Seismic Hazard Maps (NSHM) (and the hazard model from which they are derived) are first and foremost a suite of products aimed at improving earthquake-resilient construction in the United States.
The National Seismic Hazard Model calculates the likelihood and strength of earthquake shaking that may occur in different parts of Aotearoa New Zealand over specified time periods. It is critical information, used by government and industry to help improve national resilience and manage risks to safety, security and the economy from seismic ...
Jan 2, 2024 · A risk map from the 50-state NSHM 2023 update showing the greater than MMI6 for chance of damaging shaking within 100 years. Original figure by Kenneth Rukstales. This 50-state update is a time-independent probabilistic seismic hazard model.
One application of PSHA is the development of a National Seismic Hazard Model (NSHM) and the accompanying national seismic hazard maps that provide seismic design guidance at a national scale (e.g. Gerstenberger et al. 2020 and references therein).
Hazards vary throughout the country, based on the geography and ground conditions, and the frequency and types of earthquakes that might occur in each location. The model presents data in the form of hazard curves, rupture sets, maps, and reports – and you can print, download spreadsheets, and share links from the model.
Dec 29, 2023 · Maps show faults, zones applied in the CEUS, and zones of ground-motion model (GMM) amplification for the 2023 50-State National Seismic Hazard Model. The inset map is a close-up view of the New Madrid seismic zone area (orange dashed boundary).
