According to WNCT
“Underneath Yellowstone National Park in Wyoming, Montana and Idaho, there is a reservoir of magma that is more than twice the size that researchers previously thought. It’s not getting bigger. It’s just that new technology has made the ability to see it better. This will also have implications on the extent of the volcano’s impact when it erupts. Researchers with the U.S.G.S. say that the last time the volcano erupted was some 640,000 years ago. They also say that this supervolcano has the potential to spew more than 240 cubic miles of magma across Montana, Idaho and Wyoming with global effects. Scientists do believe that it will erupt again one day, but do not know when.”
The Yellowstone Caldera, to give the supervolcano its proper name, could blow anytime. But that doesn’t mean it’s due – or even overdue according to geologists.
