US supervolcano could take just decades to erupt: Study
Scientists believe the underground supervolcano at USA's Yellowstone National Park is capable of sending the Earth into a "volcanic winter". While the supervolcano hasn't erupted since the last 6.3 lakh years, scientists said, a build-up of magma and subsequent eruption would take just decades. Hence, predicting such an event early would prevent a catastrophic natural disaster, they added.
