These pictures of Pavlof Volcano in Alaska were not taken by satellite, but rather were taken by astronauts living on board the International Space Station on May 18, 2013. Pavlof volcano is located in the Aleutian Islands about 625 miles southwest of Anchorage, Alaska. The eruption started on May 13th and the amazing photographs show the ash plume migrating southeast away from the volcano toward the North Pacific Ocean. The ash cloud was roughly 20,000 feet (6,000 meters) high. Image Credits: NASA.
