Government ranks 18 US volcanoes as 'very high threat'
Government scientists have classified 18 U.S. volcanoes as "very high threat" because of what's been happening inside them and how close they are to people.

Mount Redoubt, or Redoubt Volcano, is an active and currently erupting stratovolcano in the largely volcanic Aleutian Range of the U.S. state of Alaska. It is located in the Chigmit Mountains (a subrange of the Aleutians), west of Cook Inlet, in the Kenai Peninsula Borough about 180 km (110 miles) southwest of Anchorage. The Alaska Volcano Observatory currently rates Redoubt as Aviation Alert Level Orange and Volcano Alert Level Watch. Mount Redoubt rises 9,000 feet (2,700 m) above the surrounding valleys to the north, south, and southeast in little over 5 miles (8 km); it is also the third highest within the range, with nearby Mount Torbert, at 11,413 feet, being the highest in the range and Mount Spurr at 11,070 feet being the second highest.
Active for millennia, Mount Redoubt has erupted five times since 1900: in 1902, 1922, 1966, 1989 and 2009. The eruption in 1989 spewed volcanic ash to a height of 14,000 m (45,000 ft) and managed to catch KLM Royal Dutch Airlines flight 867, a Boeing 747 aircraft, in its plume (the flight landed safely at Anchorage). The ash covered an area of about 20,000 km² (7,700 sq. miles). The 1989 eruption is also notable for being the first ever volcanic eruption to be successfully predicted by the method of long-period seismic events developed by Swiss/American volcanologist Bernard Chouet.
