Massive Deep-Sea Volcano Offers New Clues to How Earth Was Shaped ...

In the middle of the Pacific Ocean, thousands of miles from any continent, Easter Island rises out of the sea. Its surface tells a story of volcanism that began roughly 2.5 million years ago, but ...

A fiery mystery has puzzled geologists for decades: where did the lava fueling one of Earth’s largest volcanic events come from? A new study may finally have the answer. Scientists have long believed ...

A mysterious find on Easter Island, investigated by a team of geologists, suggests that the Earth's mantle seems to behave differently than once thought. Geography textbooks describe the Earth's ...

The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, ...

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

The world's largest volcano lurks beneath the Pacific Ocean, researchers announced in the journal Nature Geoscience. Called the Tamu Massif, the enormous mound dwarfs the previous record holder, ...

Buried deep under the Pacific Ocean, the Tamu Massif has been identified as the largest single volcano ever discovered on ...

The world's largest volcano lurks beneath the Pacific Ocean, researchers announced today (Sept. 5) in the journal Nature Geoscience. Called the Tamu Massif, the enormous mound dwarfs the previous ...

Geography textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ago ...
