Yellowstone's last volcanic eruption happened some 70,000 years ago, and the events weren't giant eruptions on the scale that would deposit ash over a huge swath of the U.S.

For decades, researchers in and around Yellowstone National Park have used seismic waves to map the hot mush below the Earth’s surface. Now, they're adding more to that toolkit.

Thankfully, scientists have confirmed that Yellowstone won't detonate anytime soon. A close look at the supervolcano's plumbing reveals a lack of magma stores necessary to produce an eruption.

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.

It’s still possible that the northeastern portion of the park could erupt in a massive explosive eruption similar to those that have occurred at Yellowstone in the past 2.1 million years.
