Yellowstone even more rumblings

Quote:
"We who live along Montana's Yellowstone River are downstream from a simmering caldera, a geologic hot spot that has become especially active recently. Indeed, Yellowstone National Park contains the floor of a gigantic volcanic cauldron, one that rises and sinks with the forces that lie beneath — hence the picturesque geysers and steam holes. But a wave of recent earthquake activity is raising fears that have their origins 642,000 years ago, when a Yellowstone "supervolcano" exploded so violently that it created the caldera itself. Today, such an explosion — 1,000 times more powerful than the explosion of Mount St. Helens in 1980 — would not only cover most of the U.S. with ash but also throw so much dust into the atmosphere that the world's climate could change."
