From NASAGoddard:
See one of the most eye-popping shots of a volcanic eruption ever captured from space. On June 12, 2009, a fortuitous orbit of the International Space Station (ISS) made it possible for an astronaut on board to capture Sarychev Volcano in the early stages of eruption. The volcano is located on the northwestern end of Matua Island, which is part of the Kuril Islands, a chain of 56 islands northeast of Japan. The eruption sent a plume of brown-colored ash and white steam rising into the atmosphere. The plume was so immense that it cast a large shadow on the island.
