A risk map of the 50-state NSHM 2023 update showing the greater than MMI6 for chance of damaging shaking within 100 years.

USGS National Seismic Hazard Model User-Needs Workshop

The National Seismic Hazard Model Project (NSHMP) will be summarizing the 2023 National Seismic Hazard Model (NSHM) and presenting a preliminary future vision for the 2029 NSHM release. Day 1 will consist primarily of presentations as well as discussion and questions, and Day 2 will be focused on user participation.

The 2018 update of the US National Seismic Hazard Model: Ground motion models in the western US The 2018 update of the US National Seismic Hazard Model: Ground motion models in the western US

The U.S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) is the scientific foundation of seismic design regulations in the United States and is regularly updated to consider the best available science and data. The 2018 update of the conterminous U.S. NSHM includes significant changes to the underlying ground motion models (GMMs), most of which are necessary to enable the...

The United States Geological Survey (USGS) National Seismic Hazard Model (NSHM) is the scientific foundation of seismic design regulations in the United States and is regularly updated to consider the best available science and data. The 2018 update of the conterminous US NSHM includes major changes to the underlying ground motion models (GMMs). Most of the changes are motivated by the...

The 2018 update of the US National Seismic Hazard Model: Where, why, and how much probabilistic ground motion maps changed The 2018 update of the US National Seismic Hazard Model: Where, why, and how much probabilistic ground motion maps changed

The 2018 US Geological Survey National Seismic Hazard Model (NSHM) incorporates new data and updated science to improve the underlying earthquake and ground motion forecasts for the conterminous United States. The NSHM considers many new data and component input models: (1) new earthquakes between 2013 and 2017 and updated earthquake magnitudes for some earlier earthquakes; (2) two...

A subset of CyberShake ground-motion time series for response-history analysis A subset of CyberShake ground-motion time series for response-history analysis

This manuscript describes a subset of CyberShake numerically simulated ground motions that were selected and vetted for use in engineering response-history analyses. Ground motions were selected that have seismological properties and response spectra representative of conditions in the Los Angeles area, based on disaggregation of seismic hazard. Ground motions were selected from millions...

Tall building performance-based seismic design using SCEC broadband platform site-specific ground motion simulations Tall building performance-based seismic design using SCEC broadband platform site-specific ground motion simulations

The scarcity of strong ground motion records presents a challenge for making reliable performance assessments of tall buildings whose seismic design is controlled by large-magnitude and close-distance earthquakes. This challenge can be addressed using broadband ground-motion simulation methods to generate records with site-specific characteristics of large-magnitude events. In this paper

Selecting three components of ground motions from Conditional Spectra for multiple stripe analyses Selecting three components of ground motions from Conditional Spectra for multiple stripe analyses

For complex structures where the seismic response depends appreciably on the vertical (V) component of ground motion (GM) (e.g., base-isolated buildings, long-span bridges, dams, nuclear power plants), incremental dynamic analysis (IDA) is commonly utilized to estimate seismic risk, where the V components of GM are selected and scaled based on the corresponding horizontal (H) components...
