Geoscientists have discovered a magma cap at Yellowstone National Park that is likely playing a critical role in preventing a massive eruption.

Atop the magma reservoir, researchers found a sharp, volatile-rich magma cap. The cap works like a lid on a pot, keeping the pressure and heat created down below. And by finding a defined magma cap, ...

For decades, scientists knew magma was simmering beneath the earth at Yellowstone National Park. A team of researchers ...

There, rock abruptly gives way to bubbling magma, the geoscientists found, creating a magma cap — a sign that the reservoir is dynamic and active. The data adds to existing evidence that ...
