Alaska Region

Regions L2 Landing Page Tabs

The Alaska Region represents a resource-rich, dynamic landscape shaped by volcanoes, 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.

Understanding Coastal Change

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

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.
