Unified Interior Regions
Alaska
The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanos, earthquakes, major rivers, and glaciers. Here, we conduct research to inform management of Alaska’s extensive natural resources, inform national Arctic energy policy, and provide scientific information to help others understand, respond to, and mitigate impacts from natural hazards.

Ocean Resources for America's Needs
Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.
Coastal and Marine Ecosystem Science
We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.
Conservation of native salmonids in South-Central Alaska
The proliferation of introduced northern pike in Southcentral Alaska is an urgent fishery management concern because pike are voracious predators that prey heavily on juvenile salmonids. Eradication of pike is not possible in connected freshwater networks, so managers must develop control methods that reduce pike populations to less destructive numbers. We are using field and bioenergetics...
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.
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.
Alaska Critical Minerals Cooperative
The project developed means to use several large legacy digital databases together in GIS to identify areas with mineral resource potential for critical minerals in Alaska.
Alaska Geophysical Survey Interpretation
Available geophysical data for Alaska have not been fully exploited. Project objectives were to conduct systematic analysis of existing gravity, aeromagnetic and airborne electromagnetic data to map geologic trends, structural geologic and tectonic patterns, and identify key lithologies for direct integration with geologic framework and mineral potential studies.

Residents and critical infrastructure in the nation's six highest-risk volcanic areas—including the Alaska region-- will benefit from increased monitoring and analysis as a result of Recovery Act funds being channeled into volcano monitoring, Secretary Salazar announced today.
When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick.
The eruption also provided a rare research opportunity: the chance to see how an ecosystem develops from the very first species to colonize the island.
The Pacific Ocean is the largest of the world's oceans, but relatively impoverished in many natural resources, particularly oil and gas. It is the home to a large fisheries industry that is seemingly in peril, and the place itself, a peaceful namesake, can erupt into cataclysmic disasters on a moment's notice.
Alaska's Redoubt Volcano continues to emit a plume of water vapor, gas and minor ash after its 19th successive explosion this past weekend. Scientists believe the volcano has entered a new period of cyclical lava dome growth marked by small earthquakes and intermittent tremors.
Scientists from the Alaska Volcano Observatory and the Unified Command will host a news conference at 1:00PM AKDT (5:00PM EASTERN TIME) at the USGS Alaska Science Center in the Glenn Olds Hall Conference Room, Anchorage, AK, to discuss the continuing eruption of Mount Redoubt Volcano.
High resolution photos are available on the Alaska Volcano Observatory, Redoubt Activity Web site.
Mount Redoubt Volcano, 106 miles southwest of Anchorage, Alaska, erupted explosively more than 10 times this week, sending ash skyrocketing as high as 65,000 feet into the air.
The eruption of Redoubt poses a threat to national and international aviation as volcanic ash is sent into the busy North Pacific flight paths between North America and Asia.
Scientists from the Alaska Volcano Observatory will host a news conference at 1:30PM AKDT (5:30PM EASTERN TIME) at the USGS Alaska Science Center in the Glenn Olds Hall Conference Room, Anchorage, AK, to discuss the continuing eruption of Mount Redoubt Volcano and yesterday's (March 26) overflight of the volcano.
