Scientist Working To Predict Next Supervolcanic Eruption

"Yellowstone and other volcanoes around the world are called supervolcanoes and the reason is they're like a super sized drink. It means it's just big," says Hank Hessler, a geologist at Yellowstone in the U.S. state of Wyoming.

Supervolcano describes a geological phenomenon never witnessed by man. Supervolcanoes are off the charts big when comparing them to a normal volcanic eruption.
On May 18, 1980, Mount St. Helens in the northwest corner of the United States erupted. It killed 57 people and expelled one cubic kilometer of ash.
The first Yellowstone supervolcanic eruption 2.1 million years ago was at least 25,000 times larger than the Mount St. Helens eruption. Two other Yellowstone super eruptions 1.3 million and 640,000 years ago, though smaller than the first one, would still dwarf any normal volcanic eruption.

Physicist Michio Kaku on Supervolcanos...All you can do is run!

There's trouble brewing underground and it's no joke; Physicist Michio Kaku says a supervolcano beneath Yellowstone National Park is due to erupt.

There's no way to determine precisely when the explosion will occur but scientists say the ground around the volcano has started to swell, indicating subterranean activity. It was a similar volcano that helped bring an end to the dinosaurs and this one will 'wipe out the United States as we know it', Dr. Kaku says. But Dr. Kaku is also telling people not to panic because the volcano could blow at any moment...within the next one hundred thousand years.

Hear more from Kiran Chetry's interview with Dr. Michio Kaku:

Volcanic Super-Eruption

About 74,000 years ago - long ago, but still in the realm of modern humanity - perhaps the greatest volcanic explosion ever to shake the world blew a 100km hole in the Earth's crust. The volcanic winter following the eruption at Toba in Northern Sumatra, Indonesia, tested the survival of the human race.

YELLOWSTONE SUPER-VOLCANO MAY BE IN "EARLY STAGES" OF ERUPTION!

As we review the signs -- especially the huge rock deformations that have occurred -- be advised that geologists have admitted that the Yellowstone Super-Volcano is 20,000 years past due for a major eruption. Rock deformation has already occurred that dwarfs that of Mt. St. Helens in 1980! Is this eruption the event that will deliver the planned 9.0 earthquake in Los Angeles?

Yellowstone Supervolcano Discovery—Where Will It Erupt?
New study identifies fault lines most likely to produce next eruption.

The natural beauty of Yellowstone National Park may appear serene, but it's rooted in a violent volcanic past. Now, geologists have identified which parts of the park are most likely to erupt again someday.

Yellowstone's next major eruption will probably be centered in one of three parallel fault zones running north-northwest across the park, a new study predicts.

Two of these areas produced large lava flows the last time the supervolcano was active—174,000 to 70,000 years ago—while the third has had the most frequent tremors in recent years.

(See "Yellowstone Super-Eruptions More Numerous Than Thought?")


Knowing this will help scientists determine which areas of the vast park to monitor most carefully, said study lead author Guillaume Girard, a visiting professor at Michigan State University in East Lansing.

The Yellowstone region is often referred to as a "supervolcano" because it has spewed more than 240 cubic miles (a thousand cubic kilometers) of ash and lava in a single event. The most recent of these massive blasts occurred some 640,000 years ago.

Smaller eruptions occur more frequently, said Girard, but the chance of one happening in any given year is still less than one in ten thousand. He described these eruptions as lava flows, which are not explosive: "They have very, very high viscosity and flow very, very slowly."

Similar flows have fed the slow-growing lava dome at Mount St. Helens in the years after that volcano's major eruption, but Yellowstone's lava flows occur on a much grander scale.

"Some of these flows traveled up to 20 miles [32 kilometers]," said Girard, whose study appeared in the September issue of GSA Today. "We have never seen a rhyolite eruption of this magnitude in human history."
