The new map shows where volcanic ash would fall in the event of a Yellowstone supereruption, with the supervolcano's last ...

The last super-eruption at Yellowstone volcano, which occurred 631,000 years ago, was not one huge explosion. Instead, new research suggests it was a series of eruptions or multiple vents spewing ...

And that helps “diagnose” the volcano’s current state of slumber. Map of the known ash-fall boundaries for several Yellowstone Supervolcano eruptions. Picture: USGS ...

It’s known as a super-eruption because it released an estimated 250 cubic miles of material – 1,000 times larger than the Mount St. Helens eruption in Washington state in 1980.

NASA investigated what would happen if a volcano had a super-eruption. They concluded Earth would experience limited cooling, but not be plunged into a cataclysmic volcanic winter.

For a super eruption to occur, the volcano's magma chamber, which is mostly solid, would have to push the magma up to the surface. This would be associated with a "huge amount" of seismic activity.

The Campi Flegrei volcano, near Naples in southern Italy, has crust that is becoming weaker and more prone to rupturing, "making an eruption more likely", scientists behind a new study have said.
