Interesting NASA pic... An ash eruption from above.....

"This image, acquired shortly after the beginning of the eruption, captures the ash plume moving west-southwest from the summit vent. The eruption was short-lived; the plumehad completely detached from the volcano summit two hours later. Ash plumes from Cleveland Volcano have reached heights of 12 kilometers and can present a hazard totrans-Atlantic jet flights. The fog bank visible at image top center is a common feature of the Aleutian volcanoes. Cleveland Volcano, situated on the western half of Chuginadak Island, is one of the most active of the volcanoes in the Aleutian Island chain extending west-southwest from the Alaska mainland."
