Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown

USGS scientist Neal Pastick inspects a permafrost plot in North Slope of Alaska near Galbraith Lake.
USGS scientist Burke Minsley and project partners from the U. Alaska Fairbanks lay ground cable to measure permafrost depth at Nome Creek site north of Fairbanks, Alaska.
This video presents a visualization of shaking that was recorded in the Frontier Building in Anchorage, Alaska, during the Mw7.1 earthquake, January 24, 2016, Iniskin, Alaska. It exhibits how a tall building behaves and performs during strong earthquake shaking. Note that relative to the height of the building, the motions are magnified by a factor of 300 to show...
This short clip is representative of a large amount of video footage of an adult female polar bear, equipped with a point of view camera, that is used by scientists to study polar bear behavior and feeding rates. Camera were attached to 10 animals in the southern Beaufort Sea over the course of several years, and stay on the animals for about 2 weeks until it is retrieved...

New research from the U.S. Geological Survey and partners illustrates how climate change is perceived among different generations of indigenous residents in subarctic Alaska. While all subjects agreed climate change is occurring, the older participants observed more overall changes than the younger demographic.
Two snapshots from Landsat show the extent of a landslide in an Alaska National Park.

Information relating to fish biology, locations and effects of climate change will help guide future research and management decisions
Twenty middle-school girls from Washington and Oregon are participating in the second annual “GeoGirls” outdoor volcano science program at Mount St. Helens, jointly organized by the U.S. Geological Survey and the Mount St. Helens Institute.
Information will aid marine and conservation planning
A new geologic map of the Long Valley Caldera, Mammoth Mountain, and the Middle Fork canyon of the San Joaquin River including Devils Postpile National Monument, recounts the geologic and volcanic history of the area east of the Sierra Nevada in far greater detail than any previously published report.
Alaska is a major producer of base and precious metals and has a high potential for additional undiscovered mineral resources. However, discovery is hindered by Alaska’s vast size, remoteness and rugged terrain. New methods are needed to overcome these obstacles in order to evaluate Alaska’s geology and mineral resource potential.
“The scenarios predicted by our models are encouraging in that there are clear actions that humans can take to improve the chances that healthy polar bear populations persist in the future.” - Todd Atwood, USGS
The U.S. Geological Survey has produced a new compilation of landscape-scale sediment and soil geochemical data for Alaska. This was last completed nearly 40 years ago in 1978, but the new effort uses modern modeling and analysis techniques to map 68 elements across a newly developed and updated geochemical atlas of Alaska.
“These results suggest that waterfowl populations in the western boreal forest are resilient to forest fires and that current policies of limited fire suppression have not been detrimental to waterfowl populations." – Tyler Lewis, U.S. Geological Survey.
The world’s largest volcanic eruption to happen in the past 100 years was the June 15, 1991, eruption of Mount Pinatubo in the Philippines.
