Carbon dioxide, not water, triggers explosive basaltic volcanoes

Geoscientists have long thought that water—along with shallow magma stored in Earth's crust—drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, scientists have learned that gaseous carbon ...

Mount Fuji 'under more pressure than last eruption'

Pressure in the magma chamber of Japan's Mount Fuji is now higher than it was the last time the volcano erupted more than 300 years ago, scientists say, according to a report Thursday.

Yellowstone's plumbing exposed

(PhysOrg.com) -- The most detailed seismic images yet published of the plumbing that feeds the Yellowstone supervolcano shows a plume of hot and molten rock rising at an angle from the northwest at a depth of at least 410 ...

Gas causing ground to rise near Bay of Naples volcano

New work by Italian geochemists seems to indicate that the current ground movement around one of the world's most dangerous volcano systems may be due to gas pressure, and not because of a surge of volcanic magma. This work ...

Why some planets eat their own skies

For many years, for all we knew, our solar system was alone in the universe. Then better telescopes began to reveal a treasure trove of planets circling distant stars.

How magma and water shaped the iconic Columbia River Gorge

University of Oregon researchers are adding new details to the geological history of the iconic Columbia River Gorge, a wide river canyon that cuts through the volcanic peaks of the Cascades along the border between Oregon ...

New study takes the pulse of a sleeping supervolcano

Under the volcanoes in the Andes where Chile, Argentina and Bolivia meet, there is a gigantic reservoir of molten magma. For several million years, it has been there without fully solidifying or causing a supervolcanic eruption. ...

Crystals reveal the danger of sleeping volcanoes

Most active volcanoes on Earth are dormant, meaning that they have not erupted for hundreds or even thousands of years, and are normally not considered hazardous by the local population. A team of volcanologists from the ...
