“Krakatoa was a full off caldera blast. It blew 21 cubic kilometres of ash into the stratsophere over a very short period of time.”

I wish that was on youtube.

Krakatoa was one of those things that if you were close enough to see it, you were too darn close. It blew the entire island below sea level. The island has grown back since then, but not to its original height. Of course it will go off again. The lava chamber is refilling and once it gets full Krakatoa II the sequel will become inevitable.

Of course showing a little American pride Yellowstone is a much bigger doomsday volcano than Krakatoa. When Yellowstone fires off again (600,000 year cycle, last eruption about 600,000 years ago) it will be a hard time for humanity for a few years. However Lake Toba, Sumatra, Indonesia, is the big winner. It can dump twice the volume of Yellowstone into the atmosphere. Its last blast 74,000 years ago almost took out humanity completely.
