Underneath Yellowstone National Park, magma bubbles and flows. But exactly how close it is to the surface has long been a mystery to scientists — until now. For the first time, researchers have ...

However, there are no signs of "increased volcanic unrest" at the park. The supervolcano at Yellowstone National Park has substantially more magma reservoir under the caldera than scientists ...

Scientists have worked out the consistency of the magma under the Yellowstone caldera using seismic waves — and the reservoir is filled with "mush" that doesn't pose an imminent eruption threat.

The extra magma doesn’t mean it’s more likely to erupt, scientists say. In fact, the better measurement helps them to understand its future. By Robin George Andrews Magma is the explosive ...

Scientists have discovered a giant 'magma cap' under Yellowstone National Park. The cap is likely playing a critical role in preventing a massive volcanic eruption.

Geoscientists discovered a magma cap acting as a "lid" 2.4 miles beneath Yellowstone. This magma cap traps heat and pressure, but also allows gas to vent, reducing eruption risk.
