A massive chamber holding enough magma to fill the Grand Canyon more than 11 times over is hiding beneath the steaming volcanic system of Yellowstone National Park in Wyoming.
We knew of a smaller magma chamber closer to surface, holding some 10,000 cubic kilometres of magma and feeding heat upwards. The newly discovered reservoir sits under it and has a volume of 46,000 cubic kilometres. Together, the two form the largest known magma reservoir in the world.
"We can't say definitively that this is the biggest magma reservoir in the world, but we currently don't know of any other that has been imaged that is as large as the two we see beneath Yellowstone," says Fan-Chi Lin of the University of Utah in Salt Lake City.
The discovery of the much larger reservoir at a depth of 20 to 50 kilometres helps to solve a long-running puzzle relating to the carbon dioxide spewing out from the huge steaming caldera volcano at Yellowstone, creating ripples of tiny earthquakes it does so. The problem is that the upper magma chamber is much too small to account for the 45 kilotonnes of carbon dioxide discharged daily.
"If you combine the upper and lower crustal magma reservoirs, it better accounts for the amount of carbon dioxide coming out of the ground at Yellowstone," says Lin.
... So how did we not notice this chamber before?
...
Features at the depths where the new chamber was found have been difficult to study because the speed of waves from below are dictated by rock closer to the surface. Lin's team got round this by combining readings from local, shallower, and distant, deeper tremors, allowing the distorting effects of the rocks nearer the surface to be filtered out.

Something along the lines of: The extreme weight due to the overpopulation of the North American Continent has placed such extreme pressure on the tectonic plates that it has forced magma to rise and pool under Yellowstone and will cause an eruption of such magnitude as to cause the extinction of all life from the midwest to the PAcific coast and Alaska to Mexico. We must shift the populations of all the western states equally around the globe to immediately alleviate the risk and then implement a rapid depopulation program to save the Earth from man. Long live Gaia!
Silly, don’t you know that only carbon dioxide produced by conservatives harms the environment?
It’s a scientific fact, 92% of all scientists I polled reached a consensus on that.
BUSH’S FAULT!!! HALIBURTON!!! CHENEY!!! KOCH BROTHERS!!! TEABAGGERS!!! WHITE PRIVILEGE!!!
They’re all responsible and caused this to harm women and people of color

Dr. Evil comes to mind for some reason.....
This is the one that, if it blows, will kill 75% of the people in the Western US, right?
How many times are they going to “find” this damn thing?
It is like passing school levies. Voters say “No”. Then they put it back on ballot, the “new and improved levy”, and they say “NO!”. Then “Hell No”, etc.
No one gives a hoot (nor should they).
That would be about a dozen
I'll try...
It's caused by FRACKING, obviously.
This is a thing under the thing. It’s a newly discovered thing under the thing we already knew about.
Hasn’t this been known for years?
These guys know the job:

So much for anthropogenic global warming!
That’s where I left it...
Volcano. I'm partial to the scene where Stanford "Stan" Olber carries the unconscious subway car conductor over his shoulders while the lava flows under the car. Praying, his shoes begin melting as he gets to the subway car doorway and in the end, he throws the conductor over his head to safety as he sacrifices himself, dying in the lava flow. That's a powerful, inspiring scene.
Volcano. I always enjoy movies where Los Angeles gets blowed up.
Well thanks, but I already know about the other thing because I am a nut and study such things.
Let’s face it. We’re all gonna die! LOL
The earlier thing is on top of the new thing. Cue Monty Python.
