According to the Alaska Volcano Observatory, a single explosive event sent an ash cloud up to 15,000 feet from Cleveland Volcano. Satellite images from December 29 reveal the ash cloud has detached and is drifting east/southeast from the volcano. 

Based on the presence of an ash cloud, AVO has raised the aviation color code at Cleveland Volcano to ORANGE and alert level WATCH.

Sign up for Applied Seismology - GEOS 694 - for spring semester and earn three credits! Assistant Professor of Geophysics Carl Tape of the Geophysical Institute will instruct the course that will explore the study of earthquakes and Earth's interior structure using seismological theories and algorithms. The course runs from 9:45 to 11:15 a.m. on Tuesdays and Thursdays in Elvey 301N. 

Twenty new items were added to the Keith B. Mather Library's collection in late October. The additions include a USGS professional paper co-edited by Jeff Freymueller of the Geophysical Institute's Seismology group. You can access a pdf of that paper here.

Here is a list of the new items in alphabetical order:

Essential Mathematical Methods for the Physical Sciences

Pending the arrival of the new Geophysical Institute Director Bob McCoy, Vice Chancellor for Research Mark Myers has delegated authority to GI Associate Director Doug Christensen. Christensen will provide oversight and take any needed actions required of the director position including travel approval, HR and finance issues and documents.

Upon McCoy's arrival this month, Christensen's delegation will be rescinded. At that time McCoy will assume full administrative responsibilities for the GI.

High in the Andes Mountains, a few volcanoes have been inflating for decades despite not having erupted in hundreds of thousands of years. Geophysical Institute scientists lead a South American-based project to study the world’s largest body of magma and its implications in a land of super eruptions.
