It’s that time of week again: Another report by a particularly histrionic tabloid hints that the Yellowstone supervolcano is about to erupt. Here’s a tip for you all – if the press are saying that Yellowstone is about to erupt, it definitely isn’t about to erupt. Trust us, you’d know.
The source of this latest harbinger of the not-apocalypse? A bit of a crack has formed in Grand Teton National Park in Wyoming, which is right nearby Yellowstone National Park. Therefore, we’re all going to die, right?
Of course not. This is literally just a crack, and it’s not even in the right national park.
According to a statement from park authorities, the 30 meter (roughly 100 foot) crack appeared in a bit of a large rock sticking out from a cliff. That forced a local closure for people’s safety. That’s literally it, and yet somehow outlets have linked this to the volcanological rapture.
We’re fine, but don’t take my word for it; here’s what Dr Janine Krippner, a volcanologist at Concord University and smiter of ludicrous volcanological rumors, told IFLScience: “If Yellowstone erupted every time a tabloid said it was going to, it would be one of the most active volcanoes on Earth.
“Yellowstone is, however, one of the most well-monitored volcanoes on Earth. If it were about to erupt, we would see much more than a crack appearing.”
But wait, there’s more! According to the marvelous scientists over at the United States Geological Survey (USGS), there’s a roughly one-in-730,000 chance that Yellowstone will have a supereruption in any given year.
Now, a supereruption involves the ejection of more than 1,000 cubic kilometers (240 cubic miles) of fresh volcanic material in a fairly violent manner. That’s happened at Yellowstone twice in the last 2.1 million years, with a third still colossal event not quite making the volumetric cut.
