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.

Using magnetotellurics, researchers produced a detailed picture of the magma beneath Yellowstone, offering insights into a distant future of possible volcanic activity

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.

New research reveals why the famously steamy park, hosting over 500 hot geysers, shows no signs of blowing its top. These days, the reservoirs of magma (molten rock) that feed Yellowstone hold pretty low concentrations of this magma. They simply don't contain enough volcanic fuel to drive the heat and pressure that would stoke an eruption.

Deep beneath Yellowstone National Park is an enormous volcanic crater hundreds of thousands of years old. Researchers have found a new way to track changes in the crater by studying electromagnetic fields instead of seismic activity.

It’s not hard to see why researchers are worried about a Yellowstone eruption. If the supervolcano were to erupt, the consequences would be devastating. The ashfall alone could render vast areas uninhabitable,

"This number is based simply on averaging the two intervals between the three major past eruptions at Yellowstone—this is hardly enough to make a critical judgment," the USGS Yellowstone fact sheet reads.
