The US Geological Survey says it is monitoring the area near Yellowstone National Park where a swarm of earthquakes has caused renewed concern over the area’s underground supervolcano. Although statistically unlikely, a supervolcano eruption would release the equivalent of 1,000 Hiroshima atomic bombs and wreak unprecedented destruction.
The area, West Yellowstone in Montana, reported around eleven earthquakes on Friday and a total of 34 in the last month. Though considered low-magnitude quakes, the tremors extended three miles underground.
Park officials say that earthquakes there are caused by volcanic fluids entering shallow rock fractures.
Yellowstone sits atop one of only two supervolcanos in the US. Contained within three overlapping calderas that represent past eruptions from hundreds of thousands and even millions of years ago, scientists say the Yellowstone volcano is roughly 34 by 45 miles wide and only three miles below the surface. Its last eruption was 640,000 years ago when it is estimated to have dumped over 2,000 times the amount of ash as the Mount St. Helens eruption.
However, the supervolcano eruption threat has become a predictable meme in recent years, usually resurfacing during earthquakes swarms. The reason is that if the supervolcano did go off, it would definitely be a game-changer. A BBC feature on supervolcanos described the aftermath: “The sky will darken, black rain will fall, and the Earth will be plunged into the equivalent of a nuclear winter.”
