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.
The ISS was flying 220 miles over the island of Matua when the volcano erupted in a pyroclastic flow, a howling mass of ash and gas that moves at 130 miles per hour, reaching temperatures up to 1,112ºF (600ºC). Such a terrible mayhem, yet so beautiful. [NASA]
