Off the eastern coast of Russia and north of Japan is an amazingly long 1300-km volcanic archipelago called the Kuril Chain. The weirdly rectangular Ostrov Shikotan is at the southern end, and has two extinct volcanoes on it. Tken in February 2011 by the Earth Observing-1 satellite, this photo shows icy water blown by opposing winds swirling around the island. 

I love pictures of volcanoes from space, but this one is among my very favorites.
