Researchers have come up with a new explanation for the origins of Mount Etna, which remains Europe’s most active volcano ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through a ...

An ancient underwater volcano riding a sinking tectonic plate off the coast of Japan may have unleashed several unexplained major earthquakes — by grinding against another tectonic plate above it, a ...

Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

A geologist has revealed intriguing insights into the volcanic activity on Mars. He proposes that Mars has significantly more diverse volcanism than previously realized, driven by an early form of ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science ...

Scientists say they have evidence of a new continental rift forming in southern Africa that could eventually develop into a ...

A series of relatively young underwater volcanoes has been discovered under the waves of the Pacific Ocean, some of which may even be active. The volcanoes were found during an expedition to map the ...

(photoz/Canva) 'Extinct' volcanoes that haven't erupted for tens of thousands of years may not actually be inactive, but silently accumulating huge reservoirs of magma to fuel future outbursts. This ...

A seamount sitting on a subducting tectonic plate off the coast of Japan and plowing its way into Earth's mantle may be at the root of several magnitude 7 earthquakes in the past 40 years. When you ...
