Analyzing contemporary volcanic activity with historical and geological
records of the recent past provides the context for assessing any volcano's
benefits and dangers. The Global
Volcanism Program (GVP) seeks better
understanding of all volcanoes through documenting their eruptions
during the last 10,000 years. The large and growing Volcanoes
of the World database developed by the GVP contains the geographic, historical,
and volcanological characteristics of nearly 3,000 active volcanoes
around the world. The GVP works in close collaboration with scientists
and organizations concerned with volcano hazards, airline safety, geothermal
energy, and global climate change. The database is used in research
projects and for answering questions on volcanology from other scientists,
the media, and the public. The GVP is part of the National
Museum of Natural History at the Smithsonian
Institution.
The National Atlas of the United States® extracted the
information for this map layer from the Volcanoes of the World database
described above. The map layer features volcanoes in an extended
area of the northern hemisphere centered on North America. Descriptive
information includes the name of the volcano, the timeframe of the
last known eruption, the summit elevation, the type of volcano as
described by its shape and size, and the type of evidence used to determine
volcanic activity. The National Atlas also includes a multimedia
map showing potentially active
volcanoes in the United States. Further
volcano information can be found on the U.S.
