USGS Multimedia Gallery: (Video)--Redoubt Volcano Plume

Title: Redoubt Volcano Plume

Description: Beginning in early November 2008 Redoubt Volcano, 106 miles southwest of Anchorage, AK, began to show signs of unrest including significant changes in gas emission and heat output. On November 5, 2008, the Alaska Volcano Observatory (AVO) raised Redoubt's Aviation Color Code to Yellow and the Volcano Alert Level to Advisory. A significant increase in earthquake activity caused AVO to raise the Aviation Color Code to ORANGE and Volcano Alert Level to Watch on January 25, 2009. Since November 2008 AVO staff conducted seven observation flights to monitor changes at Redoubt. Many of these flights have also served to measure the amount and types of gasses emanating from the volcano using specialized equipment. This video collected on February 7, 2009 illustrates vapor plumes emanating from holes in the newly deformed Drift Glacier near the volcanoes summit and on its north flank.
