Data Release for the 2018 Update of the U.S. National Seismic Hazard Model
The 2018 Update of the U.S. National Seismic Hazard Model defines the potential for earthquake ground shaking for various probability levels across the conterminous United States and is applied in seismic provisions of building codes, insurance rate structures, risk assessments, and other public policy. The updated model represents an assessment of the best available science in earthquake h...

3D Geologic Framework for use with the U.S. Geological Survey National Crustal Model, Phase 1: Western United States
A 3D geologic framework is presented here as part of the U.S. Geological Survey National Crustal Model for the western United States, which will be used to improve seismic hazard assessment. The framework is based on 1:250,000 to 1:1,000,000-scale state geologic maps and depths of multiple subsurface unit boundaries. The geology at or near the Earth’s surface is based on publi
Grids in support of the U.S. Geological Survey Thermal Model for Seismic Hazard Studies
A 3D temperature model is constructed in order to support the estimation of physical parameters within the USGS National Crustal Model. The crustal model is defined by a geological framework consisting of various lithologies with distinct mineral compositions. A temperature model is needed to calculate mineral density and bulk and shear modulus as a function of position within the crust. These...
Multi-hazard exposure intensity as a result of HayWired earthquake scenario mainshock (April 18, 2018) surface offset, ground shaking, landslide, liquefaction, and fire following hazards in the San Francisco Bay area, California
These data are a geospatial representation of potential multi-hazard exposure intensity for the HayWired earthquake scenario mainshock, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take existing mainshock hazard data (surface offset, ground shaking, landslide, liquefaction, and fire followin
Fire following the Mw 7.0 HayWired earthquake scenario
These data are a geospatial representation of potential damage resulting from fires following the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data take information about prevailing conditions (for example, average wind speed and direction) and potential hazard informati
