Sverhvulkany born super-fast

The eruption of supervolcanoes is the most catastrophic natural disasters that may occur on our planet, except, of course, the asteroid. Now scientists believe that these volcanoes can grow much faster than they previously thought.

It was assumed that such a process could take hundreds of thousands of years, but in fact it is enough to just a few hundred years.

This could be bad news for the U.S., where the supervolcano is located under Yellowstone National Park. If he wakes up, two thirds of the country could become uninhabitable.

Geologists think that he needs from 100,000 to 200,000 years for magma to supervolcanoes created enough pressure to explode. But new research shows that the giant magma body can type the desired effect in a few thousand or even a few hundred years.

Magma reservoir, 10 km below the Yellowstone and growing at a record pace in 2004.

The last such eruption occurred supervolcano on Earth 600,000 years ago.

Supervolcano erupted, a total of three times over the past 2.1 million years. Scientists believe that this can be repeated regularly.

The scale of the eruption at Yellowstone would be 1,000 times more powerful than the volcanic explosion that ripped Mount St. Helens in 1980.

There is also evidence that such a super eruption in Indonesia 74,000 years ago, it was close to the destruction of all humankind.

The scientists based their estimates on the crystallization of quartz. Previous studies were based on the growth of crystals of zircon, which is considered a less accurate method. They believe that regions such as Yellowstone should be monitored regularly in order to provide early warning of catastrophic eruptions.
