A Surprise From the Supervolcano Under Yellowstone 


Beneath Yellowstone National Park lies a supervolcano, a behemoth far more powerful than your average volcano. It has the ability to expel more than 1,000 cubic kilometers of rock and ash at once — 250,000 times more material than erupted from Mount St. Helens in 1980, which killed 57 people. That could blanket most of the United States in a thick layer of ash and even plunge the Earth into a volcanic winter.

Yellowstone’s last supereruption occurred 631,000 years ago. And it’s not the planet’s only buried supervolcano. Scientists suspect that a supereruption scars the planet every 100,000 years, causing many to ask when we can next expect such an explosive planet-changing event.

To answer that question, scientists are seeking lessons from Yellowstone’s past. And the results have been surprising. They show that the forces that drive these rare and violent events can move much more rapidly than volcanologists previously anticipated.

Ground around Yellowstone supervolcano has deformed | Daily Mail Online

As small earthquakes continue to rumble around the Yellowstone supervolcano in Wyoming, scientists have revealed new evidence of the changes going on beneath the ground. A new map from the US Geological Survey shows how the ground around the Yellowstone caldera has deformed over the span of two years, as the quakes release uplift-causing pressure, allowing the ground to sink back down.
