Identification_Information: Citation: Citation_Information: Originator: U.S. Geological Survey Publication_Date: 1996 Title: Volcanoes Publication_Information: Publication_Place: Reston, Virginia Publisher: U.S. Geological Survey Description: Abstract: This data set includes volcanoes thought to be active in the last 10,000 years, in and near the United States. Attributes are only attached to volcanoes in the United States and Canada. The data are a subset of data available on the World Wide Web at: http://www.volcano.si.edu/gvp/volcdata/index.htm from the Global Volcanism Program, National Museum of Natural History, Smithsonian Institution. Purpose: The digital data sets of the National Atlas are used to create electronic and hard copy maps that depict various aspects of the nation. The data can be used to conduct geographic analysis on national and large regional scales. The digital data will provide a basis from which future revisions of the atlas can be derived. Supplemental_Information: Revisions: 1) 2/26/98 - Attributes were added to the U.S., Canada, and selected offshore volcanoes. 2) 6/29/98 - Corrected ellipsoid name from WGS84 to GRS1980 and changed flattening ratio. 3) 11/13/98 - Added attribute for State FIPS code.

Data for an area around the United States were clipped. Attributes for the United States and Canadian volcanoes were attached. Tics were added and the data were converted to Lambert Azimuthal Equal Area projection.
