The Alaska Volcano Observatory (AVO) is a joint program of the United States Geological Survey (USGS), the Geophysical Institute of the University of Alaska Fairbanks (UAFGI), and the State of Alaska Division of Geological & Geophysical Surveys (DGGS). AVO monitors and studies Alaska's hazardous volcanoes, predicts and records eruptive activity, and works closely with other agencies to implement public safety measures.
