- The seismic hazard maps address this need by integrating what scientists have learned about earthquake sources, crustal deformation, active faulting, and ground shaking. This information is translated into a form that can be used to reduce the risk from earthquakes and to improve public safety.

Jan 2, 2024 · The U.S. National Seismic Hazard Model (NSHM) relies on deformation models to assign slip rates along active faults used in the earthquake rupture forecast. Here, we present the geologic deformation model results in tabular form.
Dec 29, 2023 · The 2023 US 50-State National Seismic Hazard Model: Overview and implications. The US National Seismic Hazard Model (NSHM) was updated in 2023 for all 50 states using new science on seismicity, fault ruptures, ground motions, and probabilistic techniques to produce a standard of practice for public policy and other engineering applications ...
the national seismic hazard maps for the UK. This is to take account of advances in seismic hazard methodology since the last seismic hazard maps were developed by Musson and Sargeant (2007) and present the results in a format that will be compatible with the future Eurocode 8 revisions.

The SSC model aims to describe the location, size, and frequency of future earthquakes through a set of parameters such as the geometry of the seismic sources, maximum earth-quake magnitude, and recurrence parameters drawn from the FMD of the seismicity in each source (e.g. Budnitz et al. 1997).
Dec 29, 2023 · The USGS National Seismic Hazard Model (NSHM, Petersen et al., 2020) forms the underlying ground-shaking hazard layer applied in this risk assessment and is made by developing the nation’s fault and fold deformation databases, interpreting crustal and volcanic seismicity, and evaluating the probabilistic ground-shaking levels for various ...
