sawedIf the supervolcano underneath Yellowstone National Park ever had another massive eruption, it could send ash for thousands of miles across the United States, smothering crops and shutting down flights and power plants all over. It’d likely be a disaster. But that doesn’t mean we should all start freaking out. The odds of that happening are thankfully pretty low. 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. And despite what you sometimes hear in the press, there’s no indication that we’re due for another “super-eruption” anytime soon. In fact, it’s even possible that Yellowstone might never have an eruption that large again. Even so, the Yellowstone supervolcano remains an endless source of apocalyptic fascination — and it’s not hard to see why. Last week, a team of scientists published a paper in Geochemistry, Geophysics, Geosystemsexploring what a Yellowstone super-eruption might actually look like. Among other things, they found the volcano was capable of blanketing the northern Rockies in three feet of ash and could spread material as far as Miami and Washington, DC. More
