In this photo released by the Alaska Volcano Observatory/U.S. Geological Survey, steam rises from the top vent in the summit crater of Alaska's Mount Redoubt, Saturday March 21, 2009. The Mount Redoubt volcano erupted five times Sunday night and early Monday morning, March 22 and 23, 2009, sending an ash plume more than 9 miles into the air in the volcano's first emissions in nearly 20 years.
