U.S. Volcano Information

There are 169 potentially active volcanoes in the U.S., and the USGS Volcano Hazards Program provides warnings of unrest and eruption for these volcanoes. We offer volcano monitoring data, provide maps and geologic information, conduct research how volcanoes work, and engage with community education and outreach.

Alaska Volcano Observatory (AVO)

The AVO is a partnership among the USGS, the Geophysical Institute of the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys. To mitigate volcanic hazards, AVO monitors and studies Alaska's hazardous volcanoes to forecast and record eruptive activity. AVO also monitors volcanic activity in the Commonwealth of the Northern Mariana Islands.

Annotated photo of Bogoslof Island showing effects of eruption

Annotated photograph of Bogoslof Island showing the cumulative effects of 2016-17 eruptive activity. A layer of fine muddy appearing ash drapes most of the landscape and covers pre-existing vegetation. The dashed line indicates the area excavated by explosive eruptive activity so far. A prominent zone of upwelling is probably the surface expression of a shallow submarine vent. Photograph taken...

Caribou, North America’s wild reindeer, have lives apart from their famous role on Christmas Eve. Reindeer and caribou are large, cold-adapted, herding herbivores related to deer, elk and moose.

To learn more about how these arctic antler-bearers spend the other 364 days of the year, we talked to USGS caribou expert Dr. Layne Adams, who has studied these animals for more than 30 years.
