Horrible Today: Live Footage Seconds" Yellowstone Massive supervolcano explosion, Threaten Millions
Past volcanic eruptions that have taken place at Yellowstone National Park have been global disasters. Today, scientists are trying to predict how this ticking time bomb will explode-or fizzle out. The Yellowstone supervolcano last erupted about 640,000 years ago. A gigantic volcano lies under the western United States. For the last 70,000 years, it has been mostly quiet. If that ever changes, it could be devastating.
The "supervolcano" is located beneath Yellowstone National Park, which is a giant park that extends through Wyoming, Idaho, and Montana. The volcano itself is in northwestern Wyoming. About 6-10 kilometers (4-6 miles) beneath the ground is a large chamber filled with magma, or molten rock.
Volcanologists, or scientists who study volcanoes, have been observing the supervolcano since 1923. Recently, the volcano has been more active than usual. Some scientists wonder if that means it might erupt soon. The eruption of such a large volcano could cause serious damage.
