A new study may finally have the answer. Scientists have long believed that underwater volcanic hotspots—where hot, chemically distinct rock rises from deep inside the planet—form massive ...

A new study traces a 120-million-year-old 'super-eruption' to its source, offering new insights into Earth's complex geological history. Geologists led by the University of Maryland and the ...

"We had to sample deeply submerged volcanoes from a different long-lived hotspot track to find evidence from tens of millions of years ago that suggested our models for the Pacific plate needed ...

A fiery mystery has puzzled geologists for decades: where did the lava fueling one of Earth’s largest volcanic events come ...

Sometimes eruptions are explosive and lava is thrown out as volcanic bombs. Hotspots are places where the magma rises up through the crust. They are caused by a static source of magma, often away ...

The volcano, known as Axial Seamount, is formed by a hotspot in Earth's mantle. Axial Seamount poses no threat to the public, as it sits too deep in the ocean and too far from shore to cause any ...

“Where did things go?” Eventually it clicked: He and the sub’s other passengers were witnessing the tail end of a submarine volcanic eruption that had entombed the flourishing ecosystem ...

“We had to sample deeply submerged volcanoes from a different long-lived hotspot track to find evidence from tens of millions of years ago that suggested our models for the Pacific plate needed ...

High in the Central Andes, a geological enigma lies dormant. Uturuncu volcano in Bolivia hasn't erupted in over 250,000 years. It is also known as a "zombie" volcano because it still exhibits ...

Does seismic activity under this long-dead volcano mean it’s about to rise from the grave? That’s what an international research team set out to discover as this Bolivian “zombie” volcano continues to ...
