A NASA thought experiment called, Defending Human Civilisation From Supervolcanic Eruptions, stated that a supervolcano eruption was more likely to happen in the future than an asteroid hitting the earth, according to the Daily Star. It said: “Supervolcanic eruptions occur more frequently than a large asteroid or comet impacts that would have a similarly catastrophic effect to human civilization.” Jet Propulsion Laboratory researchers found that collisions from asteroids which are more than 2km in diameter occurred “half as often as supervolcanic eruptions”.

Yellowstone Caldera is classed as a supervolcano which erupted 60,000 years ago and again 60,000 years before that.

Although there is no guarantee, if the volcano follows the same pattern then it is now due for another eruption.

Researchers have found that if a supervolcano like Yellowstone did erupt, then a “volcanic winter” would ensue which could surpass the “amount of stored food worldwide”.

People living on another continent would not be spared from the aftermath of a supervolcanic eruption.
