Earlier this year scientists used new technology to more accurately map the magma system that powers the super volcano beneath Yellowstone. They discovered an additional poop of magma below the originally pool. This new pool is over 4 times larger then the shallower one, which when you combine the two, you can fill The Grand Canyon 13 times over. The scientists warn that there is still nothing to worry about as the chances of the volcano erupting in any year is 1 in 700,000.
