Scientists at NASA have developed a hugely ambitious strategy to counter the looming threat of an apocalyptic supereruption from the Yellowstone Caldera.
Yellowstone is one of about 20 known supervolcanoes around the world, and an eruption from any of these could produce so much fiery magma that the ensuing ash cloud might starve the Earth of sunlight in a choking, years-long volcanic winter.
Against such a backdrop, NASA has been working on a plan to counter this potentially far off but ultimately inevitable circumstance, which could be graver than even the nightmare scenario of a planet-devastating asteroid strike.
“I was a member of the NASA Advisory Council on Planetary Defence which studied ways for NASA to defend the planet from asteroids and comets,” researcher Brian Wilcox from the space agency’s Jet Propulsion Laboratory told the BBC.
“I came to the conclusion during that study that the supervolcano threat is substantially greater than the asteroid or comet threat.”
As recently as 2011, NASA was downplaying the immediate risks of supereruptions, given the staggeringly long timeframes between which they occur – roughly every 100,000 to 1 million years.
