The data release for the geologic terranes of the Hailey 1 x 2 degrees quadrangle and the western part of the Idaho Falls 1 x 2 degrees quadrangle, south-central Idaho is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Bulletin 2064-A (Worl and Johnson, 1995). The updated digital data present the attribute tables and geospatial features (lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plate and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image,...

The U.S. Geological Survey, in cooperation with the U.S. Department of Energy, conducted a study on the magnetic record contained in subsurface basalts within coreholes at the Idaho National Laboratory. Standard 1 inch paleomagnetism core samples were collected from 11 coreholes. The samples were characterized for polarity and average paleomagnetic inclinations over the entire length of the drill core. However, paleomagnetic declination data were not obtained due to the original azimuth of the drill cores not being preserved during drilling. The samples were extracted from individual lava flows based on identification of flow tops and bottoms in the drill core. These samples were then transported to the USGS Paleomagnetic...

The California volcano locations, threat rank and hazard zones data release contains two shapefiles for download or use as a web map service. The California Volcanic Center Locations shapefile was created to provide a generalized location of volcano hazard sources. The California Volcano Hazard Zones shapefile was created from previously published hazard zone reports. Specific details about each file can be found in the metadata included with each file and the read-me document for this data release. Together, these files were used to define California Volcano Hazards for the GIS analysis that supports conclusions in the California's exposure to volcano hazards report. Geologists produce hazard zone maps to convey...
