Awesome!

(Full size here) This is certainly among the most amazing and stunning volcanic eruption images I have ever seen. According to the description of the image, "A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev Volcano (Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009."

The plume of ash from this eruption has diverted numerous flights in the north Pacific region, and has forced quite a number to simply return to their point of origin; they didn't have enough fuel to safely divert around the plume. The blogger who brought this picture to my attention, Eric Klemmeti, has been following the eruption regularly under the category "Sarychev" on his blog, Eruptions.
