What is the biggest supervolcano in the world?
Yellowstone
The largest (super) eruption at Yellowstone (2.1 million years ago) had a volume of 2,450 cubic kilometers. Like many other caldera-forming volcanoes, most of Yellowstone’s many eruptions have been smaller than VEI 8 supereruptions, so it is confusing to categorize Yellowstone as a “supervolcano.”
What would happen if Yellowstone’s supervolcano erupted?
If the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could spew ash for thousands of miles across the United States, damaging buildings, smothering crops, and shutting down power plants. In fact, it’s even possible that Yellowstone might never have an eruption that large again.
How big is the magma chamber under Yellowstone?
about 40 by 80 kilometers across
The magma chamber is believed to be about 40 by 80 kilometers across, similar in size to the overlying Yellowstone caldera. The top of the chamber is about 8 km deep and the bottom is around 16 km deep. However, the chamber is not completely filled with fluid magma.
How deep has the magma pipe been imaged beneath Yellowstone?
12 to 28 miles
April 23, 2015 – University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber.
Will Yellowstone supervolcano destroy the world?
The Yellowstone supervolcano is a natural disaster that we cannot prepare for, it would bring the world to its knees and destroy life as we know it. This Yellowstone Volcano has been dated to be as old as 2,100,000 years old, and throughout that lifetime has erupted on average every 600,000-700,000 years.
Is Yellowstone the largest super volcano in World?
The United Nations world heritage site, which lies over giant chambers of molten magma, is actually the world’s largest super volcano , which erupted 2.1 million, 1.3m and 640,000 years ago, causing massive devastation across the planet. Today, Yellowstone bubbles away with its hot springs and geysers with endearing names.
Why is Yellowstone called a super volcano?
The reason Yellowstone is considered a supervolcano is because, as numerous online sources and the previous answer all point out, there is a ton of hot water under the Yellowstone park. That kind of climate could create a disastrous event if it were to explode.
The magma chamber is believed to be about 40 by 80 kilometers across, similar in size to the overlying Yellowstone caldera. The top of the chamber is about 8 km deep and the bottom is around 16 km deep.
Is Yellowstone Volcano a dangerous volcano?
Volcanic Hazards at Yellowstone. The Yellowstone Plateau in the northern Rocky Mountains in Wyoming, Montana, and Idaho is centered on a youthful, active volcanic system with subterranean magma (molten rock), boiling, pressurized waters, and a variety of active faults with significant earthquake hazard. Graphic representing the frequency of hazardous events that occur at Yellowstone.
