Where can I find information about volcanoes in Alaska?

Alaska contains over 130 volcanoes and volcanic fields which have been active within the last two million years. Of these volcanoes more than 50 have been active within historical time (since about 1760, for Alaska).

Visit the Alaska Volcano Observatory (AVO) for information on Alaska Volcanoes. The Alaska Volcano Observatory (AVO) covers volcanoes in Alaska from offices in Anchorage and Fairbanks, Alaska, and is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.
