Mount Redoubt (Alaska)

Encyclopedia : M : MO : MOU : Mount Redoubt (Alaska)


Mount Redoubt, or Redoubt Volcano, is an active volcano and is the highest peak in the Aleutian Range on the Alaska Peninsula in Alaska. It is located in the Chigmit Mountains (a subrange of the Aleutians), west of Cook Inlet, about 180 km (110 miles) southwest of Anchorage, Alaska.

Mount Redoubt erupted in 1966 and again in 1989. The eruption in 1989 spewed volcanic ash to a height of 14,000 m (45,000 feet) and managed to catch a KLM 747 aircraft in its ash plume (the aircraft landed safely at Anchorage). The ash covered an area of about 20,000 km² (7700 sq. miles).

Mount Redoubt is not a particularly steep peak, but it is a massive mountain: it rises 9000 feet above the surrounding valleys to the north, south, and southeast in little over 5 miles.
