The supervolcano beneath Yellowstone National Park is much, much larger than was previously believed.

A new study shows the volcano’s magma chamber about 2.5 times larger than previous estimates suggested, stretching more than 55 miles and containing about 125 and 185 billion cubic miles of molten rock.

The cavern is about 20 miles wide and nearly 2 miles deep.

“We’ve been working there for a long time, and we’ve always thought it would be bigger,” said Bob Smith, University of Utah professor. “But this finding is astounding.”

The findings were presented this week at theAmerican Geophysical Union Fall Meeting in San Francisco.

“We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground,” said Dr. Jamie Farrell, of the University of Utah. “The waves travel slower through hot and partially molten material (and) with this, we can measure what’s beneath.”

The last major eruption 640,000 years ago covered North America with ash and affected the climate of the entire planet. An eruption today would be catastrophic for the entire planet

The magma chamber extended much further east than previously believed, holding a mixture of solid and molten rock.

“To our knowledge there has been nothing mapped of that size before,” Farrell said.

But the larger size does not necessarily make the Yellowstone hazard greater, Smith said.

Researchers can’t say for sure when the volcano might erupt again, but they monitor the area for advance warning of seismic activity.

Some believe that a massive eruption is overdue because the Yellowstone volcano erupts every 700,000 years or so.

Previous known eruptions occurred about 2 million years ago and 1.3 million years ago.

Previous eruptions of the Yellowstone supervolcano have occurred 2,000,000 years ago, 1,300,000 years ago, and 640,000 years ago. I know eruption intervals aren't always exact  (they seldom are) on volcanoes...but how is the volcano overdue for an eruption when it hasn't even reached the typical 700,000 year mark yet? There are a few things we should remember if it does erupt in our time. First, it will likely end civilization as we know it since it would likely turn the day to night for about three to five years and likely jumpstart the next ice age. Second, even if they can predict it, there is nothing they can do to prevent it or mitigate the results. Third, the closer to the equator you live, the more chance of survival you have (but it will likely be cold even at the equator). Your chances for survival increase if you still have the ability to produce and/or store food. Without that, you are doomed...so learn how to farm.

Going to stockpile Vodka. Wait have already done that,  same as for every weekend. Thing is gone by Monday..

 

Actually not very worried about apocalyptic event. Given what life would be like I'd rather go out in a happy haze..

Quite the typo there.  The volume of the entire planet in cubic miles is approximately 260 billion.  If the chamber is 55 miles by 20 miles by 2 miles as said in the article, that is 2,200 cubic miles.  They likely were trying to compute cubic yards or meters?  There are 4.11 billion cubic meters to the cubic mile, so that math doesn't work either.  Oh well.  Still, that is an immense magma chamber, and when it goes off, adios civilization as we know it.

They make this predicted average based on 2 data points?

They didn't say how deep it was so maybe they are including the entire core of the Earth?

Yellowstone super volcano eruption 'would affect the world' as scientists discover it is even bigger than they thought
  • Cavern of molten lava is up to 9 miles deep and 55 miles across

 

 

don't worry, hollywood says you can outrun it.

ever had a pimple so big it came out the other side?... daaamn

Sounds to me like a fear tactic so the government will throw more money at them to study it more.

 

Hell it worked for those climate guys why not them too.

It might wipe out America, but I am not so sure about affecting civilisation. lol

Sign? What sign?

 

Yellowstone swim break on a hot July day.

Actually...no. The hotspot that is under Yellowstone now is stationary, but the North American plate has steadily moved westward across it. For that reason, there are over a dozen giant lava flows that provide a track from Eastern Oregon, all the way up the Snake River Valley in Idaho to its present position in Northwest Wyoming. For some reason, the movement has slowed in the last couple of million years, allowing the caldera to erupt three times in essentially the same place (Yellowstone), but the fact that that magma pool has spread to the East indicates that the North American plate is once again on the move. The point is that the history of eruptions caused by this hotspot is much longer than the three eruptions in the Yellowstone area (I think that means there are three data points right there). The eruptions from Eastern Oregon across Idaho have also been dated and calculated into the average eruption interval.
