The supervolcano that lies beneath Yellowstone National Park in the US is far larger than was previously thought. A study shows that the magma chamber is about 2.5 times bigger than earlier estimates suggested.
A team found the cavern stretches for more than 90km (55 miles) and contains 200-600 cubic km of molten rock.
The team found that the magma chamber was colossal. Reaching depths of between 2km and 15km (1 to 9 miles), the cavern was about 90km (55 miles) long and 30km (20 miles) wide.
It pushed further into the north east of the park than other studies had previously shown, holding a mixture of solid and molten rock.
