Latest Study: Yellowstone Supervolcano May Erupt Sooner Than Expected, Lead to ‘Volcanic Winter’


NASA believes that the Yellowstone supervolcano is a greater threat to life on Earth than any other potential natural disaster, including plummeting asteroids. So it’s working on a plan.

LETTING OFF STEAM

NASA’s researchers have told the BBC they have explored what it would take to avert a super volcano catastrophe.

The answer: find a way to cool the magma down.

Supervolcanos only spill over when the molten rock is hot enough to become highly fluid.

In a slightly cooler state, it gets thicker. Stickier.

It’s not going anywhere fast.

To achieve this, the Jet Propulsion Labs team calculated a super volcano on the brink of eruption would have to be cooled some 35 per cent.

They propose to do this by pricking the supervolcano’s surface, to let off steam.

But this in itself poses risks.

Drill too deep, and the vent could cause an explosive depressurisation that may set off the exact kind of eruption the scientists were trying to avoid.

Instead, the NASA scientists propose, a 10km deep hole into the hydrothermal water below and to the sides of the magma chamber. These fluids, which form Yellowstone’s famous heat pools and geysers, already drain some 60-70 per cent of the heat from the magma chamber below.

NASA proposes that, in an emergency, this enormous body of heated water can be injected with cooler water, extracting yet more heat.

This could prevent the super volcano’s magma from reaching the temperature at which it would erupt.

Such a project could cost in excess of $3.5 billion. But it’s nothing like the reconstruction cost of digging two thirds of the continental United States out from under mountains of volcanic ash.

And it could even help pay for itself.

Steam from the superheated water could be used to drive power turbines.

“You would pay back your initial investment, and get electricity which can power the surrounding area for a period of potentially tens of thousands of years,” NASA’s Brian Wilcox says.
