When the dinosaur-snuffing asteroid hit Earth some 66 million years ago, it produced a subterranean pool of magma roughly nine times larger than the current caldera at Yellowstone National Park, ...

The 2021 "Fagradalsfjall Fires" eruptions may have been triggered by magma pooling just underneath the ground, contrary to what scientists initially thought. An eruption of the Fagradalsfjall volcano ...

WASHINGTON — A vast pool of molten rock in the continental crust that underlies southwestern Washington state could supply magma to three active volcanoes in the Cascade Mountains — Mount St. Helens, ...

The supervolcano below Long Valley, California, near Yosemite National Park hasn't erupted in 765,000 years—but when it did, if geologists had been around to watch it, they may have been surprised by ...

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. Seismic imaging and ...

Volcanos are releasing ash and smoke into the atmosphere on three continents. That might be making you think back to your elementary school science class when you probably studied volcanoes and lava.

Molten rock is accumulating in a magma chamber beneath New Zealand, raising questions about volcanic hazards. Ian Hamling and his colleagues at GNS Science in Lower Hutt, New Zealand, used satellite ...

The loss of the magma played a crucial role in the moon's landscape formation. There was once a magma-filled ocean on the south pole of the moon, scientists recently discovered after analyzing lunar ...
