i like the ones that are actually plausible. the ones about ancient mayan curses and the lighthouse one, etc, are just silly. oh, and yellowstone last erupted 640,000 years ago, and before that it was 1.3 million years ago, and before that 2.2 million years ago. it's estimated to erupt every 700,000 years on average, but there is such a wide range of possibility that nobody knows. remember that we're talking huge numbers of years here, and that, to emphasize the scale of these numbers, the roman empire fell less than 2000 years ago. usgs scientists say "The probability of a large caldera-forming eruption within the next few thousand years is exceedingly low."
it wouldn't necessarily end humanity, considering that a complex ecosystem survived its last eruption, but it certainly wouldn't be a good thing for us.
