Volcano Hazards Assessments Help Mitigate Disasters

The Volcano Hazards Program develops long-range volcano hazards assessments. These includes a summary of the specific hazards, their impact areas, and a map showing ground-hazard zones. The assessments are also critical for planning long-term land-use and effective emergency-response measures, especially when a volcano begins to show signs of unrest.

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.

USGS California Volcano Observatory (CalVO)

CalVO operates real-time volcano monitoring networks, disseminates forecasts and notifications of significant activity, assesses volcano hazards, researches volcano processes, and works with communities to prepare for volcanic eruptions in California and Nevada. The Observatory is located at USGS offices in Menlo Park, California.

Cascades Volcano Observatory (CVO)

The CVO staff conduct research on many aspects of active volcanism, respond to dangerous volcanic activity in many parts of the world, and maintain a close watch over volcanoes in Washington, Oregon and Idaho. The USGS established CVO in Vancouver, Washington, after the May 18, 1980, eruption of Mount St. Helens.

Hawaiian Volcano Observatory (HVO)

HVO operates monitoring networks, assesses hazards, and issues notifications of volcanic activity and earthquakes in the State of Hawai‘i. HVO scientists conduct fundamental research on volcanic processes and work to educate the communities at risk. HVO is located in Hawaiʻi Volcanoes National Park on the Island of Hawaii.

Yellowstone Volcano Observatory (YVO)

Monitors and studies the active geologic processes and hazards of the Yellowstone Plateau volcanic field and its caldera. Yellowstone National Park contains the largest and most diverse collection of natural thermal features in the world. YVO also monitors volcanic activity in Montana, Wyoming, Colorado, Utah, and New Mexico.
