Yellowstone Supervolcano Making Strange Rumblings 411
Frosty Piss writes "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. Significant activity continues beneath the surface. And the activity has been increasing lately, scientists have discovered. In addition, the nearby Teton Range of mountains is somehow getting shorter. The findings, reported this month in the Journal of Journal of Geophysical Research, suggest that a slow and gradual movement of a volcano over time can shape a landscape more than a violent eruption."

Correct, and it could be another 160,000 years.
Last huge eruptions:
640,000 years ago
1,300,000 years ago
2,100,000 years ago
Last 2 time gaps:
660,000 years
800,000 years
I don't know where the "600,000 years" often-quoted average number came from, this is too small based on recent history.
Anyone losing sleep over this is a lunatic.
Much more possible is a smaller eruption. Of course, even a "small" Mt. St. Helens size event is pretty disruptive.

Of course, IANAVolcanologist, all I know is what I saw on the one BBC show about it.
