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.

Multichannel seismic-reflection profile, Sitka Sound

Multichannel seismic-reflection profile showing deformed and offset sediment layers below the outer continental shelf west of Sitka. The Sitka Sound fault is one of more than a dozen previously unmapped faults discovered in the July 2017 seismic-reflection data. Location of profile shown by yellow line on trackline map, above. km, kilometer; m, meter; s, second.

USGS Public Lecture: Warm Ice—Dynamics of Rapidly Changing Glaciers

  • Glacier Numerology – The how big, how long, how thick, how much, how often, of glacier science.
  • Glacier Photography – While a picture may be worth a thousand words, a collection of images may tell a complete forensic story.
  • Glacier Geophysics – How new technologies are being introduced to reexamine and refine decades old glacier analyses.

America’s rivers and streams are generally suitable for irrigation, supplying drinking water, and home and recreational uses. However, in areas with significant agricultural and urban development, the quality of our nation’s water resources has been degraded by contaminants such as pesticides, nutrients, and gasoline-related compounds.

It was the earthquake that woke up America, its 9.2 Herculean shaking reverberating through the earth, causing the whole planet to ring like a bell for weeks afterward. Even now, the earth is still moving in response to the "Good Friday Earthquake" that rocked Alaska on March 27, 1964.

The rapid depletion of at least a half million great whales from the North Pacific Ocean by intensive industrial whaling over 50 years ago may have unleashed a complex ecological chain reaction that has since rippled resoundingly from ocean to coastal ecosystems, according to a team of eight scientists, including Dr. Jim Estes, a U.S. Geological Survey research ecologist.
