Resource Abstract:
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 the northern hemisphere centered on the United States. The data are a subset of data available from the Global Volcanism Program, Smithsonian Institution at <http://www.volcano.si.edu/world/>. This file is a replacement for the November 2001 map layer.

Band
descriptor The volcano number, based on a system developed by the Catalog of Active Volcanoes of the World (CAVW), in the format ####-##-. The first two numerals identify the region, the next two identify the subregion, and the last two or three (after the hyphen) identify individual volcanoes in that subregion. When there are three final characters and the last character is "=", the number is the same as that found in the CAVW; where the last character is "-", the number is not found in the CAVW because the region was not numbered in the CAVW or has been renumbered for this map layer; where the last character is a number, the volcano is in an area included in the CAVW but the number is a new one that does not appear in the CAVW. See <http://www.volcano.si.edu/world/globallists.cfm?listpage=summdesc#VolcanoNumber> for more information.
