The Mayon volcano in the Philippines has erupted nearly 40 times in 400 years, and it looks primed to go off again. This NASA satellite image shows a small plume of ash or steam blowing west from its summit.
Back in June, astronauts onboard the International Space Station took a few spectacular photos of the Sarychev Peak volcano as it exploded in a 5-mile high plume of ash and gas. Here's the even more spectacular video.
On June 12th, Saychev Peak on Matua Island erupted, hurling ash and steam into the air. Luckily, NASA's International Space Station was watching. This stunning image, from the Earth Observatory, reveals some rare details about this eruption.
