Here is a gif of what it looked like from the ISS.
A picture of Russia's Sarychev Volcano, on Matua Island in the Kuril Islands, erupting on 12 June 2009, as seen from the International Space Station (ISS). The ISS orbits the Earth at a height of between 347 and 360 km.
Original description by NASA: "A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev volcano (Russia’s Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. Sarychev Peak is one of the most active volcanoes in the Kuril Island chain and is located on the northwestern end of Matua Island.

So I'm guessing the force of the eruption is what split the clouds and created that circle? Or was it the smoke plume piercing through?
