<p>This map layer includes Holocene volcanoes, which are those thought to be active in the last 10,000 years, that are within an extended area of<br/></p><p>the northern hemisphere centered on the United States. The data are a<br/></p><p>subset of data available from the Global Volcanism Program, Smithsonian<br/></p><p>Institution at <http://www.volcano.si.edu/world/summary.cfm>. This<br/></p><p>file is a replacement for the April 2004 map layer.<br/></p><p><br/></p><p>These data are intended for geographic display and analysis at the<br/></p><p>national level, and for large regional areas. The data should be<br/></p><p>displayed and analyzed at scales appropriate for 1:2,000,000-scale<br/></p><p>data. No responsibility is assumed by the National Atlas of the<br/></p><p>United States in the use of these data.<br/></p><p><br/></p><p>Further information on the Global Volcanism Program of the<br/></p><p>Smithsonian Institution is available at <http://www.volcano.si.edu/>.<br/></p><p><br/></p><p>A glossary of volcano terminology is available at<br/></p><p><http://vulcan.wr.usgs.gov/Glossary/volcano_terminology.html>.<br/></p>
