Yellowstone Volcano Could Blow on Short Notice

Yellowstone Volcano Could Blow on Short Notice

As if we didn’t have enough on our plates, now we know that Yellowstone’s supervolcano doesn’t need much time to get ready to blow.

Studies of fossilized ash from the most recent eruption 630,000 years ago show that the heat and pressure leading up to it built quickly. It took decades, rather than centuries, to trigger the last explosion.

Hannah Shamloo, a co-author of the study, stated that “It’s shocking how little time is required to take a volcanic system from being quiet and sitting there to the edge of an eruption.”

Yellowstone is one of the best-monitored volcanoes on the planet, and right now it still seems to be quiet. So if anything changes, we’ll know—hopefully, in time.
