Magma is the molten material beneath the Earth's crust. It usually collects in a magma chamber beneath a volcano, and can then be injected into cracks in rocks or issue out of volcanoes in eruptions.

Researchers show that magma chambers under supervolcanoes are more like soggy sponges than reservoirs of molten rock. Before a volcano of this kind erupts, such mush must slowly be reactivated by heat ...

The future of geology — and maybe even renewable energy — is heating up, literally. Scientists in Iceland are steaming ahead with an ambitious project to drill straight down into a magma chamber that ...

In an effort to better understand volcanic activity and its origins on Earth and beyond, University researchers have examined the creation of magma chambers to help explain why these chambers exist at ...

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, ...

Volcanoes, with their fiery eruptions and molten rivers, have captivated humanity for millennia. But some volcanoes lurk in silence, biding their time, and hold the potential for eruptions so vast ...

(Inside Science) -- On a bright day in 1981, John Eichelberger stood on a blackened crust above billions of gallons of lava. Plumes of steam leaked from cracks in the basalt surface, driven upward by ...

The project, which would be a scientific first if successful, would see boreholes drilled about 1.3 miles down through the earth’s crust at a volcano known as Krafla, located in the northeast of ...

Volcanoes have stirred human awe for thousands of years, with their bursts of fire and rivers of molten rock. Yet, beyond the familiar cone-shaped peaks lies a more silent, hidden ...
