ALASKA VOLCANO PICTURES: Redoubt Erupts

ALASKA VOLCANO PICTURES:  Redoubt Erupts
<< Previous   6 of 6    
A building near the mouth of Alaska's Drift River lies buried in volcanic flood debris from the 1989-90 eruptions of nearby Redoubt Volcano on June 1, 1990. During those sustained eruptions, ash mixed with melted snow and ice to create dramatic floods called lahars.

With Redoubt once again erupting as of March 22, 2009, the National Weather Service has issued an ashfall advisory for some towns north of Anchorage and is warning residents to seal doors and windows, protect electronics, and minimize driving. And eruption-induced mudflows have once again been seen in the Drift River, said Tina Neal of the Alska Volcano Observatory.
