3D Geologic Framework for use with the U.S. Geological Survey National Crustal Model for Seismic Hazard Studies (ver. 2.0, September 2025) 3D Geologic Framework for use with the U.S. Geological Survey National Crustal Model for Seismic Hazard Studies (ver. 2.0, September 2025)
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 published maps...
