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, ...

Researchers discovered that the tremors in Greece were not caused by a slipping fault but were triggered by rebounding sheets of magma slicing through the Earth’s crust.

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, ...

Supervolcanoes with the power to destroy human civilisations may have much shorter fuses than was previously thought, scientists believe. The news could be bad for the US, where a supervolcano is said ...

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 ...

The largest pocket of molten rock on Earth has driven up a region in the Andes to form the world's second highest continental plateau. The body of magma is more than a kilometre deep and hundreds of ...

If Mars conceals a lake beneath its south polar ice cap, the planet must also have a hidden chamber of magma to keep the water liquid, a new analysis suggests. Signs of a 20-kilometer-wide lake, ...

One theory held that the earth’s crust under the sea was and is formed at mid-ocean ridges from a single magma layer spread around the middle of the earth’s crust That’s now changed to the ...

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 largest volcanoes on our planet may take as little as a few hundred years to form and erupt. These "supervolcanoes" were thought to exist for as much as 200,000 ...
