The biggest badest volcano of them all is right here in the good old USA,Yellowstone, and it goes off large about every 600,000 years. And the last large eruption was, you guessed it, 600,000 years ago.

As long as Yellowstone continues to vent it is not that big a worry. It is when it doesn't vent that we should worry. That said, what is the evidence for repeated super-volcanos. I'm not saying, but only speculating that they could be one time events...where the explosion destroys the process leading to the vent in the first place.

Nah. It's over due. It erupted 640,000 years ago.
