Magnitude 9.2: The 1964 Great Alaska Earthquake is a short video relating how the largest quake in U.S. history had profound and lasting impacts on our lives. The video features USGS geologist George Plafker who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory...
An HVO geologist shields his face from the intense heat as he takes a sample of active lava on the Kahaualeʻa 2 flow, Kilauea Volcano Hawaii. The chemistry of the lava is analyzed through time and used to study changes in the magmatic system.

Aerial view toward the southwest of the actively erupting cone within Veniaminof caldera. The white steam plume is produced where a lava flow is descending the side of the cone and melting snow and ice. The darker colored, ashy plume is rising in bursts from the active vent. Nearly continuous eruption from this vent since early June has built a new small tephra cone and an...

Rapidly changing glaciers in Alaska demonstrate tight physical and ecological linkages with downstream ecosystems that bridge the icefield-to-ocean continuum. This talk will highlight recent efforts of an Alaska Climate Science Center supported research project to better understand these linkages, including how glaciers influence hydrology and oceanography as well as the...
ANCHORAGE, Alaska Melting glaciers are not just impacting sea level, they are also affecting the flow of organic carbon to the world’s oceans, according to new research that provides the first ever global-scale estimates for the storage and release of organic carbon from glaciers.
ANCHORAGE, Alaska — In a new polar bear study published today, scientists from around the Arctic have shown that recent generations of polar bears are moving towards areas with more persistent year-round sea ice.
Secretary of the Interior Sally Jewell announced today that Interior’s Alaska Climate Science Center is awarding more than $500,000 to universities and other partners for research to guide managers of parks, refuges and other cultural and natural resources in planning how to help species and ecosystems adapt to climate change.
ANCHORAGE, Alaska — A polar bear capture and release-based research program had no adverse long-term effects on feeding behavior, body condition, and reproduction, according to a new study by the U.S. Geological Survey.
In a new polar bear study published today, scientists from the United States and Canada found that during the first decade of the 21st century, the number of polar bears in the southern Beaufort Sea experienced a sharp decline of approximately 40 percent.
The Pacific walrus population roughly halved between 1981 and 1999, the last year for which demographic data are available. A recent study by scientists at the U.S. Geological Survey quantifies this historic population decline.
As of Wednesday afternoon, August 13, all power issues were resolved and the U.S. Geological Survey Hawaiian Volcano Observatory resumed monitoring volcanoes and earthquakes.
Alaska — Due to climate change, some communities in rural Alaska and the Yukon Territory of Canada may face a future with fewer caribou according to new research published by the U.S. Geological Survey and the University of Alaska, Fairbanks in the recent issue of PLoS ONE.
Starting on July 5 (weather permitting), U.S. Geological Survey scientists will conduct a high-resolution airborne survey over the next 30 days to study the distribution of minerals exposed at the surface in various parts of Alaska.
The first "point of view" video from a polar bear on Arctic sea ice has just become available courtesy of the U.S. Geological Survey.
The U.S. Geological Survey is reducing its footprint on the Alaska Pacific University campus by closing the Map Store @ USGS to lower rent costs. The store will remain open through Oct. 31, 2014.
Ever since the great magnitude 9.2 earthquake shook Alaska 50 years ago today, scientists have suspected that the quake's rupture halted at the southwestern tip of Kodiak Island due to a natural barrier.
