"This oblique image (looking at an angle) from the International Space Station (ISS) captures an ash cloud first observed on satellite imagery at 11:00 GMT on August 14, 2006. An ISS astronaut took this picture one hour and 45 minutes later. The ash cloud caused the Buenos Aires Volcanic Ash Advisory Center to issue an aviation hazard warning." Link. (Thanks, Spluch)
Reader comment:
Evan Thoms of the U.S. Geological Survey, PNW mapping project says,
Earlier this summer my wife, Michelle Coombs, was acting as Duty Scientist at the Alaska Volcano Observatory (AVO) when she got a phone call from the ISS to report an eruption in the Aleutian Islands. She spoke with astronaut Jeff Williams for a few minutes while she and and others at AVO determined it was a volcano called Mt. Cleveland. Jeff later sent them this picture.
This and many other amazing photos of Alaskan volcanoes are available from the excellent AVO website.
