Mt. Redoubt update

Scientific American has put together an interesting slide show of images from the Mount Redoubt eruption.

The volcano has moved to a more steady, but less explosive, eruption pattern.

And there are web cams of the volcano available here and here.

Mt. Redoubt's eruption in 1990: A dramatic, mushroom-shaped eruption column rises above Mt. Redoubt on April 21, 1990. Clouds of this shape, which are produced when the upper part of an eruption column attains neutral buoyancy and is spread out above the troposphere-stratosphere boundary, are common during powerful explosive eruptions.

From the Earth Observatory website:

NASA’s Landsat 5 satellite captured this true-color image of Redoubt Volcano and its immediate surroundings on March 26, 2009. Against the backdrop of a snowy landscape, the volcano’s steam plume must be found by its texture rather than its color. Above the volcano summit, the vapor billows like giant balls of cotton. On either side of the steam plume, brown volcanic ash appears. Although some of the ash is probably airborne (a large swath of airborne ash appears in a wider view of the area acquired on the same day), some of the ash has settled on the ground. Settled ash is especially apparent east of the plume, where small ridges appear surrounded by darker ash. North of the volcano summit, the lahar appears nearly black, narrowing into the Drift River Valley.
