Yellowstone’s last supereruption was around 640,000 years ago, and geologists say there’s an “exceedingly low” chance that a supereruption would happen in the next few thousand years— or possibly ever again. So don't worry. You can enjoy your Yellowstone trip in peace!

Sage: Is the Yellowstone volcano going to erupt again? 

You might have heard Yellowstone described as a "supervolcano," which could cause colossal destruction if it erupted again. 

But "supervolcano" isn't really a scientific term, technically. 

A "supervolcano" is one that's had at least one supereruption, which is an 8 or higher on the Volcanic Explosivity Index. 

Yellowstone's last super eruption was around 640,000 years ago, and geologists say there's an "exceedingly low" chance that a supereruption would happen in the next thousand years, or possibly ever again. 

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

Volcanologists keep tabs on the amount of magma held within the volcano's underground reservoir.

Right now, that magma's spread across lots of smaller underground pockets, and not linked up enough to erupt in one big boom. 

So, no worries. Enjoy your Yellowstone trip in peace.
