Yellowstone Volcano Bigger Than Estimated
A supervolcano located in Yellowstone National Park is much more super than previously thought. The new study from the University of Utah found that the supervolcano is 2.5 times bigger than earlier estimates, stretching a massive 55 miles. Using seismometers to collect data, they found that the volcano’s chamber is 18 miles wide and runs three to nine miles below the Earth. If (God forbid) it did erupt, they say it would be a “global event.” Its largest blast was 2,000 times the size of the 1980 eruption of Mount S. Helens and another eruption like that would spew large amounts of material into the atmosphere, where it would circle the Earth.
