Alaska's Mount Redoubt

Beginning March 22nd, 2009, Alaska's Mount Redoubt, began a series of volcanic eruptions, and continues to be active to this date. Ash clouds produced by Redoubt have pushed 65,000 feet into the sky, disrupting air traffic, drifting across Cook Inlet, and depositing layers of gritty ash on populated areas of the Kenai Peninsula and Anchorage, about 180 km (110 miles) to the northeast. Mount Redoubt has erupted at least five times since 1900, with the most recent event taking place in 1989.
