The USGS requests that the earthquake hazard community bring to our attention new earthquake source and ground motion data or models that could be included in the NSHM updates. In addition, workshops are held for feedback and comments. The National Seismic Hazard Model will be updated twice over the next 6 years since the 2014 update. View NSHM Schedule 2016-2021.
Design Ground Motions
Ground motion parameter values for building and bridge design.
Seismic Hazard Maps and Other Products
U.S. Seismic Hazard Maps, hazard tools, and other products.
Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Also, generalized fault data used in the hazard maps.
Earthquake Scenarios describe the expected ground motions and effects of specific hypothetical large earthquakes.
