Yellowstone National Parks Supervolcano May Blow Much Sooner Than Thought

"SNIP..........


Researchers analyzing minerals in fossilized ash from the most recent mega-eruption of Yellowstone National Park’s supervolcano say that it is due to blow up again much sooner than previously thought—and may wipe life off Earth in a matter of decades, National Geographic reports.

The Arizona State University researchers have found that the supervolcano could potentially send out more than 1,000 cubic kilometers of ash, which is 2,500 times more material than blew from Mount St. Helens in 1980, The New York Times reports. This could cover most of the United States and force the entire planet into a volcanic winter.

The supervolcano’s last giant eruption was over 630,000 years ago. This event created the 40-mile bowl that spans the Yellowstone park. This is not Earth’s only dormant supervolcano. Scientists guess that a supereruption occurs roughly every 100,000 years.

Geologists assumed that it would take hundreds of years for the next supervolcanic eruption—until now. The ASU researchers found in their analysis temperature changes and composition that have taken mere decades, instead of the expected centuries, and scientists are now realizing that the conditions that contribute to supereruptions could show within one lifetime.

affected. Is this what white supremacists mean when they worry about the destruction of the white race?

The west will get hit hardest although shortly after it wouldn't make much of a difference. Scary stuff though.

Saw a PBS show couple of years back, which said if there is enough pressure it could be like a nuke and would devastate the entire county.

“The scientists at the U.S. Geological Survey's Yellowstone Volcano Observatory reassure that there isn't anything unusual going on under the park, and that the odds are that it won't erupt for centuries. But when the volcano eventually does blow, they say, it's going to be a gigantic event that will spew enough ash to blanket the Rocky Mountains with a layer that could be several feet thick, and send particles across the entire country, with some even reaching far-away cities such as New York and Washington, D.C.”

“Beneath Yellowstone National Park lies a supervolcano, a behemoth far more powerful than your average volcano. It has the ability to expel more than 1,000 cubic kilometers of rock and ash at once — 2,500 times more material than erupted from Mount St. Helens in 1980, which killed 57 people. That could blanket most of the United States in a thick layer of ash and even plunge the Earth into a volcanic winter.”

Like maybe enough time to say, "What was that noise?".

Just like it did the previous times it erupted? Oh, wait – that's right, those eruptions didn't.
