The data are a subset of data available from the Global Volcanism Program, Smithsonian Institution at . This file is a replacement for the November 2001 map layer. Purpose: These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:2,000,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data. Supplemental_Information: Further information on the Global Volcanism Program of the Smithsonian Institution is available at . A glossary of volcano terminology is available at .
