Alaska's Mount Redoubt volcano began erupting on March 22, 2009, and activity continued for several months.
During the eruptions, reports found ash clouds reaching as high as 65,000 feet (20,000 m) above sea level. In response, the National Weather Service issued a series of ash fall advisories. The Mat-Su Valley, Anchorage, Valdez and large portions of the Kenai Peninsula all received coatings of tephra. The 2009 eruptions of Mount Redoubt represented the most seismic activity occurring on the mountain in twenty years.
