London: The molten rock that lies beneath the Yellowstone National Park is much larger than previously thought, according to a new study.

Lead author Jamie Farrell of the University of Utah said the magma chamber is about 2.5 times bigger than what the earlier estimates suggested.

Researchers used a network of seismometers situated around the park to map the magma chamber and found that the cavern stretched for more than 55 miles and contained 200-600 cubic km of molten rock.

Professor Bob Smith, from the University of Utah, said that they`d been working there for a long time, and they always thought that it was going to be bigger but the finding was astounding.
