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. 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 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."
