Supervolcanoes can sleep for centuries or millennia before producing incredibly massive eruptions that can drop ash across an entire continent.

One of the largest supervolcanoes in the world lies beneath Yellowstone National Park, which spans parts of Wyoming, Montana and Idaho.
Though the Yellowstone system is active and expected to eventually blow its top, scientists don't think it will erupt any time soon.

Yet significant activity continues beneath the surface. And the activity has been increasing lately, scientists have discovered. In addition, the nearby Teton Range of mountains, in a total surprise, is getting shorter.

The findings, reported this month in the Journal of Geophysical Research — Solid Earth, suggest that a slow and gradual movement of a volcano over time can shape a landscape more than a violent eruption.

With Yellowstone it's not if but when. there are a few other super volcano;s around the world like this. When 1 goes off it instant global climate change. Maybe Algore can come up with a law to ban super volcanos
