Corked Volcano Researchers have found evidence that a giant "lid" made of magma could be stopping the supervolcano in Yellowstone National Park from erupting. As detailed in a paper published in the journal Nature last month, a team of researchers discovered a "volatile-rich cap" a mere 2.36 miles below the surface, trapping pressure and heat below it. In fact, the researchers believe the obstruction may be what's causing the volcanic system from erupting. "For decades, we’ve known there’s magma beneath Yellowstone, but the exact depth and structure of its upper boundary has been a big question," said team colead and […]
