So this has just happened recently…(see above and go wow)
A little info about the volcano…
Reventador is an active stratovolcano which lies in the eastern Andes of Ecuador. It lies in a remote area of the national park of the same name. Since 1541 it has erupted over 25 times, although its isolated location means that many of its eruptions have gone unreported. Its most recent eruption was in 2009, but the largest historical eruption occurred in 2002. During that eruption the plume from the volcano reached a height of 17 km and pyroclastic flows went up to 7 km from the cone.
Here are some more amazing images you simply cannot ignore.
