This method allowed scientists to locate the top of Yellowstone’s magma chamber. They found it sits about 3.8 kilometers (12,500 feet) below the surface.

Beneath Yellowstone National Park lies something extraordinary—a giant underground chamber filled with molten rock, trapped gases, and intense heat. For years, scientists have known about this ...

Experts are warning that hundreds of dormant volcanoes around the world will likely become more active and erupt thanks to ...

“The Yellowstone system is one that’s been stagnant for a long time.” The volcano’s largest eruption, which earned it the title of a supervolcano, occurred 2.1 million years ago.

That’s something scientists would be able to detect. They also found rapid movement of magma into a small chamber is likely to produce an eruption capable of being detected, not one without warning.

Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones ...

A spot in eastern Africa called the Afar Triangle marks the meeting point of three rift zones—lines where Earth’s crust is being rent apart. Researchers haven’t been sure exactly what drives this ...

Geologists have developed a new mathematical method that can estimate magma pressure beneath the Earth's surface using only the visible portions of ancient volcanic dykes. The tool, developed by a ...

When the island of Santorini was rattled by thousands of small earthquakes earlier this year, many people were left mystified ...

Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are ...
