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.
