Giant Volcano Unusually Active

"The Independent" reports that a recent study has found that the caldera under Yellowstone National Park is rising at around three inches a year. The implications of this are not totally clear, but what is a little nerve-racking is the fact that this volcano underneath Yellowstone is one of the largest extant volcanos on earth. It being very active is kind of worrying. The last major eruption was 640,000 years ago so the chances of it erupting within our lifetime are pretty slim. But scientists seem to think that this mega-volcano erupts in 640,000 year cycles - what a coincidence - which means that we are due for another world shaking eruption about now. Keep your eyes open for an explosion 2,500 times greater than that of Mt. St. Helens in 1980.
