Yellowstone National Park, known for erupting geysers like Old Faithful, is home to one of earth’s largest volcanic systems, with the capacity to wreak havoc on an entire continent — and components of that so-called supervolcano are on the move, experts say.

New mapping of the magma lying beneath Yellowstone National Park sheds light on where volcanic activity is shifting, and the likelihood of a full-scale eruption.

Yellowstone National Park is one of the most popular tourist destinations in the US, but it is also home to one of the world's largest active volcanic systems

Yellowstone has hosted "supereruptions" — the most explosive type of volcanic blast that would be regionally devastating, and blanket a large swathe of the U.S. in ash. These blasts were much larger than any in recorded history.
