If the supervolcano underneath Yellowstone National Park ever had another massive super-eruption it would be very bad — though also pretty unlikely. Odds are very high that Yellowstone will be eruption-free for the coming centuries.
The Yellowstone supervolcano — thousands of times more powerful than a regular volcano — has only had three truly enormous eruptions in history. One occurred 2.1 million years ago, one 1.3 million years ago, and one 664,000 years ago. There’s no indication that we’re due for another “super-eruption” anytime soon.
