New research suggests high water content in magma can significantly reduce the risk that a volcano will explode. That's not what experts thought.

New findings get researchers "one step closer to improving the monitoring of volcanic unrest, which aims to protect lives, infrastructure, and crops."

Erupting volcanoes, and not a geologic or chemical process, may have led to the first puff of oxygen in the atmopshere of the early Earth.

Examining the collapse of the erupting volcano Kīlauea's caldera allowed researchers to confirm current ideas about friction's role at earthquake faults.

"If you send a spacecraft to the surface of Venus, which has been done several times, they only last a few minutes until the hot acid burns them up."

"Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle..."

Concrete gave us the Pantheon and the Hoover Dam, but it's a huge contributor to global warming. Replacing just one ingredient could change that.

Volcanoes may have erupted on Mars as recently as 50,000 years ago. The finding raises the possibility of recently habitable conditions below the surface.

New research digs into ferrovolcanism, volcanoes on planets made of metal. It could give us a glimpse at what those metallic worlds might look like.

A new analysis of rock samples brought back from NASA's Apollo missions help clear up questions about the moon's formation and lava-covered early years.
