The Plume of the Cleveland Volcano as Seen From Space.

This photo was taken on May 23, 2006 by Flight Engineer Jeff Williams of the International Space Station:

This picture shows the ash plume moving west-southwest from the volcano’s summit. A bank of fog (upper right) is a common feature around the Aleutian Islands. The event proved to be short-lived; two hours later, the plume had completely detached from the volcano (see image from May 24). The AVO reported that the ash cloud height could have been as high as 6,000 meters (20,000 feet) above sea level.

Cleveland Volcano, situated on the western half of Chuginadak Island, is one of the most active of the volcanoes in the Aleutian Islands, which extend west-southwest from the Alaska mainland.
