Geologists were astonished after they recently discovered that the size of the supervolcano beneath Yellowstone National Park is far bigger than previously thought. A new study revealed that the magma chamber of the supervolcano beneath Yellowstone is about 2.5 times larger than earlier estimates.
Yellowstone National Park is known worldwide for its wide variety of wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. However, few are aware of the supervolcano beneath Yellowstone which, if it erupts, could cause worldwide climate damage and even wipe out the U.S.
