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 and Geophysical Surveys (ADGGS).[3] AVO was formed in 1988, and uses federal, state, and university resources to monitor and study Alaska's volcanology, hazardous volcanoes, to predict and record eruptive activity, and to mitigate volcanic hazards to life and property. The Observatory website allows users to monitor active volcanoes, with seismographs and webcameras that update regularly. AVO now monitors more than 20 volcanoes in Cook Inlet, which is close to Alaskan population centers, and the Aleutian Arc due to the hazard that plumes of ash pose to aviation.[4]

Monitored volcanoes
editThe following list shows volcanoes regularly monitored by the Alaska Volcano Observatory using activity detection instruments. While the majority of these volcanoes are in remote locations and would only pose a threat to aviation, there are a few in some areas that could have an impact on populated communities.[9]
- Akutan Peak on Akutan Island in the Fox Islands group
- Aniakchak Crater in Aniakchak National Monument and Preserve on the Alaska Peninsula (includes Aniakchak Peak and Vent Mountain)

The following list shows select volcanoes monitored by AVO but currently do not have activity detection instruments and generally rely on satellite and local observations. These primarily include volcanoes that have had eruptions or other volcanic activity in recent years. Such monitoring is not limited to the volcanoes listed below and more could be added in the future if necessary.[9][11]

- Davidof Volcano on Davidof Island in the Rat Islands group
- Fourpeaked Mountain in the Aleutian Range within Katmai National Park and Preserve
- Kasatochi Volcano on Kasatochi Island in the Andreanof Islands group
- Kiska Volcano on Kiska Island in the Rat Islands group
- Mount Chiginagak on the Alaska Peninsula near Ugashik
- Mount Douglas in the Aleutian Range within Katmai National Park and Preserve
- Seguam Volcano on Seguam Island in the Andreanof Islands group (includes Pyre Peak)
