Volcanic Eruption

Sarychev Peak has a habit of erupting every decade or so, and the International Space Station happened to be flying overhead when it spewed an ash plume high into the sky on July 12, 2009. The Russian volcano, located in the Kuril Islands northeast of Japan, is believed to have released a shockwave that blasted a hole in the cloud cover, offering the ISS a clear view of the roiling plume capped by a pileus cloud - the same type of cloud seen atop the mushroom clouds of some high-yield nuclear detonations. The ash plume cast shadows on the clouds below it, disrupted air traffic, and offered us a spectacle for the ages.
