How to pronounce“supereruption”in English

But a supereruption is VEI of 8, meaning it ejects at least 1000 cubic kilometers of ash, pumice, and debris.

Even if a supereruption were going to happen at Yellowstone, we'd have some notice.

But just because supereruptions aren’t much of a threat to us, doesn’t mean regular old volcanic eruptions aren’t.

Because this placid lake formed from a massive volcanic supereruption.

And geologists say there’s an “exceedingly low” chance that a supereruption would happen in the next few thousand years.

Technically, a “supervolcano” is a volcano that’s had at least one supereruption, like the one that formed Lake Taupō.

But the last supereruption at Yellowstone was around 640,000 years ago.

So, you have geologists’ blessing— you can take a Yellowstone supereruption off your Things to Worry About list.

And just because a volcano has had one, or even two, supereruptions in the past, doesn't mean its future blasts will be as hefty.
