Yellowstone Supervolcano Even Bigger Than We Realized
The Washington Post reports that the "supervolcano" beneath Yellowstone National Park (which, thankfully, did not kill us all in 2004, or in 2008 ) may be more dangerous when it does erupt than anyone realized until recently. Scientists have today published a paper documenting their discovery of an even
larger, deeper pool of magma below the already huge reservoir near the surface. From the article:
On Thursday, a team from the University of Utah published a study, in the journal Science, that for the first time offers a complete diagram of the plumbing of the Yellowstone volcanic system.
The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber. The newly discovered reservoir is 4.5 times larger than the chamber above it. There's enough magma there to fill the Grand Canyon. The reservoir is on top of a long plume of magma that emerges from deep within the Earth's mantle. ...
“This is like a giant conduit. It starts down at 1,000 kilometers. It's a pipe that starts down in the Earth," said Robert Smith, emeritus professor of geophysics at the University of Utah and a co-author of the new paper. ... The next major, calderic eruption could be within the boundaries of the park, northeast of the old caldera. “If you have this crustal magma system that is beneath the pre-Cambrian rocks, eventually if you get enough fluid in that system, enough magma, you can create another caldera, another set of giant explosions," Smith said. "There’s no reason to think it couldn’t continue that same process and repeat that process to the northeast.”
Where's the kaboom? There was supposed to be an earth shattering kaboom.
I have a question. Just what is being consumed to keep such a monstrous magma chamber X2 burning? Coal? Oil? something is keeping it molten.
The souls of the damned.
Why don't we just put a giant heatsink on it?
Or we could go with radiators for maximum Earth overclocking!

Just wait for winter, it'll snow a lot at Yellowstone and that should put the volcano out.

I read that the first time as 5 million.
Had me in a bit of a panic for a moment.

Maybe you will. I plan to live forever, possibly as a fish, or maybe a sentient brassiere.
