Do you remember that one of the 2012 end times predictions was an eruption of the supercaldera under Yellowstone National Park? Needless to say, that didn’t happen, but that’s not to say it never will. Scientists have discovered a vast reservoir of molten magma under Yellowstone. Really vast. New Scientist reports on the implications:

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.
