Exploring USGS volcano observatories—Part 2: Alaska...

Detailed Description

Redoubt Volcano, shown here on April 4, 2009, is just one of the more than 50 historically active volcanoes monitored by the Alaska Volcano Observatory (AVO). Gray ash draping the flanks of the volcano creates a stark contrast to the surrounding snow-covered landscape and white steam rising from Redoubt's summit crater. INSET: The USGS office of AVO, located in Grace Hall on the Alaska Pacific University campus in Anchorage, coordinates the observatory's operations. Other AVO offices are at the University of Alaska and the Alaska Division of Geological and Geophysical Surveys in Fairbanks. USGS photos.
