 In the past decade, earthquake scientists have discovered a family of unusually slow earthquakes.  These slow earthquakes occur in diverse geologic environments.  Like ordinary earthquakes, they occur as slip on the same faults that host ordinary earthquakes, but they take a long time to unfold, such that they can be described as "slow." Their discovery was enabled by...

Little Sitkin Volcano, a 3,898-foot-stratovolcano near the end of the Aleutian Chain, is exhibiting signs of elevated unrest and scientists with the Alaska Volcano Observatory have put the volcano on color code yellow. According to the latest AVO report, a swarm of high-frequency earthquakes began at 7:15 p.m. Alaska Daylight Time on August 29, 2012. The anomolous seismic activity continued...

 In late July, Jeff Freymueller was named as the new Alaska Volcano Observatory Coordinating Scientist. The decision was made among administrators with the Geophysical Institute, the U.S. Geological Survey and the Alaska Division of Geological and Geophysical Surveys. Freymueller is currently a professor of geophysics. He joined the Geophysical Institute faculty in 1995. He earned his...

 By Ned Rozell On June 6, 1912, if you happened to be sitting on a log outside your cabin near Fairbanks, Juneau or Dawson City, you would have heard an explosion. There was no way to know the boom came from hundreds of miles away, or that it was the starting gun for the largest volcanic eruption of the 1900s. Nor would you imagine that in the next three days a mountain would...

The Alaska Earthquake Information Center, based at the Geophysical Institute at the Unviersity of Alaska Fairbanks, collects earthquake data from a network of more than 400 seismic sites. Their job is to not only collect event data, but analyze and archive it for the State of Alaska, other agencies and the general public. Although Alaska is always rumbling with some seismic activity, recent...

Centered just 38 miles south/southeast of Kantishna, Alaska, a magnitude 3.01 earthquake rumbled on April 27, 2012. The earthquake occurred at 4:36 a.m. It was just one of four temblors that rocked the state of a magnitude 3 or greater on this date.  Stay informed on the latest seismic activity in state by visiting the Alaska Earthquake information Center site here.

The Interior rumbled early this morning with a sizeable quake. With an epicenter just 35 miles west of Fairbanks, a 3.83 earthquake occurred at 1:21 a.m. April 11, 2012. Since that initial temblor, a number of minor quakes continue to rattle the center of the state. A quick count on the Alaska Earthquake Information Center's Recent Earthquakes map show an additional 19 minor quakes have occurred...

The Alaska Volcano Observatory changed the Aviation Color Code of Iliamna Volcano to Yellow on Friday, March 9. Over the past three months the earthquake rate at the volcano has steadily increased and now exceeds normal background levels. Although it is not certain that this sustained increase in earthquake activity represents the movement of magma at depth, it is a significant change and AVO has...

 Following apparent explosive activity and a resultant small ash cloud on February 18, 2012, the Alaska Volcano Observatory elevated the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY for Kanaga Volcano in Alaska's Aleutians. Volcanic tremor had been detected on the local seismic network at Kanaga, followed by numerous small events for about an hour. Short-lived...
