In a recently published study, researchers revealed their 3-D map of Yellowstone’s underground system--the first of its kind--including a new massive reservoir of magma.
While Yellowstone’s supervolcano has been researched and mapped before, a new study has uncovered a previously unknown magma reservoir.
According to research led by the University of Utah, the newly discovered body of magma lies 12 to 28 miles below Yellowstone with a volume of 11,200-cubic-miles, the equivalent of 11.2 times the Grand Canyon.
A previously discovered chamber, located above it at about 3 to 9 miles underground, has 4.4 times less capacity, or 2.5 times the Grand Canyon
