2014 Update of the Pacific Northwest portion of the U.S. National Seismic Hazard Maps 2014 Update of the Pacific Northwest portion of the U.S. National Seismic Hazard Maps

Several aspects of the earthquake characterization were changed for the Pacific Northwest portion of the 2014 update of the national seismic hazard maps, reflecting recent scientific findings. New logic trees were developed for the recurrence parameters of M8-9 earthquakes on the Cascadia subduction zone (CSZ) and for the eastern edge of their rupture zones. These logic trees reflect...

Seismic hazard in the Intermountain West Seismic hazard in the Intermountain West

The 2014 national seismic-hazard model for the conterminous United States incorporates new scientific results and important model adjustments. The current model includes updates to the historical catalog, which is spatially smoothed using both fixed-length and adaptive-length smoothing kernels. Fault-source characterization improved by adding faults, revising rates of activity, and...

Seismic source characterization for the 2014 update of the U.S. National Seismic Hazard Model Seismic source characterization for the 2014 update of the U.S. National Seismic Hazard Model

We present the updated seismic source characterization (SSC) for the 2014 update of the National Seismic Hazard Model (NSHM) for the conterminous United States. Construction of the seismic source models employs the methodology that was developed for the 1996 NSHM but includes new and updated data, data types, source models, and source parameters that reflect the current state of...

The 2014 United States National Seismic Hazard Model The 2014 United States National Seismic Hazard Model

New seismic hazard maps have been developed for the conterminous United States using the latest data, models, and methods available for assessing earthquake hazard. The hazard models incorporate new information on earthquake rupture behavior observed in recent earthquakes; fault studies that use both geologic and geodetic strain rate data; earthquake catalogs through 2012 that include...

Ground motion models used in the 2014 U.S. National Seismic Hazard Maps Ground motion models used in the 2014 U.S. National Seismic Hazard Maps

The National Seismic Hazard Maps (NSHMs) are an important component of seismic design regulations in the United States. This paper compares hazard using the new suite of ground motion models (GMMs) relative to hazard using the suite of GMMs applied in the previous version of the maps. The new source characterization models are used for both cases. A previous paper (Rezaeian et al. 2014)...

Earthquake shaking hazard estimates and exposure changes in the conterminous United States Earthquake shaking hazard estimates and exposure changes in the conterminous United States

A large portion of the population of the United States lives in areas vulnerable to earthquake hazards. This investigation aims to quantify population and infrastructure exposure within the conterminous U.S. that are subjected to varying levels of earthquake ground motions by systematically analyzing the last four cycles of the U.S. Geological Survey's (USGS) National Seismic Hazard...

Hazard map from the 2023 50-state update of the National Seismic Hazard Model Project

New USGS map shows where damaging earthquakes are most likely to occur in US New USGS map shows where damaging earthquakes are most likely to occur in US

USGS scientists and our partners recently revealed the latest National Seismic Hazard Model, showing that nearly 75% of the United States could experience a damaging earthquake, emphasizing seismic hazards span a significant part of the country.
