Summary
The U.S. Geological Survey, California Volcano Observatory (CalVO) in collaboration with the State of California Governor’s Office of Emergency Services and the California Geological Survey, are working to understand the State’s exposure to volcanic hazards by integrating volcanic hazard information with geospatial data on at-risk populations, infrastructure, and resources. These data are from the geospatial analysis of the assets against volcano hazard zones (near vent, lava flow, lahar, flood, and ash fall) for California volcanoes ranked as Moderate, High, or Very High Threat in the US Geological Survey's 2005 report entitled “Volcanic Threat and Monitoring Capabilities in the United States” available on-line at http://pubs.usgs.gov/of/2005/1164/.

Summary
The U.S. Geological Survey, California Volcano Observatory (CalVO) in collaboration with the State of California Governor’s Office of Emergency Services and the California Geological Survey, are working to understand the State’s exposure to volcanic hazards by integrating volcanic hazard information with geospatial data on at-risk populations, infrastructure, and resources. These data are from the geospatial analysis of the assets against volcano hazard zones (near vent, lava flow, lahar, flood, and ash fall) for California volcanoes ranked as Moderate, High, or Very High Threat in the US Geological Survey's 2005 report entitled “Volcanic Threat and Monitoring Capabilities in the United States” available on-line at http://pubs.usgs.gov/of/2005/1164/. These data, in tabular format, are intended for use in GIS software applications and other standalone spreadsheet applications.
Volcanic threat is defined in the 2005 report as the the combination of hazards (the dangerous or destructive natural phenomena produced by a volcano) and exposure (the people, property, and resources at risk from the volcanic phenomena). The U.S. Geological Survey has systematically assessed hazard and exposure factors to calculate an overall threat score for the 169 U.S. volcanoes that are either currently in an eruptive phase, show signs of unrest due to magma at depth, or those young enough to be capable of reawakening (eruptions within the past 10,000 years). Pertinent to this metadata compilation are the volcanic hazard exposure data for Moderate-to-Very High threat volcanoes including Medicine Lake Volcano, Mount Shasta, Lassen Volcanic Center, Long Valley Volcanic Region, Clear Lake Volcanic Field, Ubehebe Craters, and Salton Buttes.
