A yellow, brick-like volcanic formation found nearly 10,000 feet deep reveals how underwater eruptions fracture rock.

Mass extinction events throughout Earth’s history are characterized as significant disruptions to life on the planet. There ...

Learn how geological clues preserved in ancient oceans link repeated volcanic eruptions to Triassic marine extinctions.

A swelling underwater volcano off the West Coast may erupt later than previously projected. Scientists initially thought that the Axial Seamount, which lies 300 miles off the coast of Oregon, would ...

A swelling underwater volcano off the West Coast is now expected to erupt later than previously projected. Scientists initially thought that the Axial Seamount, which lies 300 miles off the coast of ...

Ancient marine extinctions, previously a mystery, are now linked to massive underwater volcanic eruptions in the Tethys Ocean. Rocks from Tibet, once the seafloor, reveal chemical signatures of these ...

Submarine volcanoes, volcanic structures hidden beneath the ocean surface, play a vital role in shaping Earth’s geology and marine ecosystems. Formed through tectonic plate movements, rising magma, ...

Scientists are predicting that a mile-long volcano off the U.S. West Coast will erupt this year. The Axial Seamount, an underwater volcano located about 300 miles off the coast of Oregon, is ...

WELLINGTON, New Zealand — New Zealand and Australia have sent military surveillance flights to assess the damage in Tonga caused by Saturday's huge undersea volcanic eruption. Communications with the ...

SAN FRANCISCO — Though volcanoes dot the face of the planet and can be found on every continent, researchers say most of Earth's volcanic eruptions happen in a dark and faraway place: deep underwater.

New studies suggests that the ice ages influence underwater volcanic eruptions. Because volcanic chains spread across 37,000 miles (59,500 kilometers) on the ocean floor, the eruptions could pump out ...

Analysis has shown a boulder weighing almost 1,200 tons in Tonga is one of the largest known wave-transported rocks in the world, providing new insights into the Pacific region's history and risk of ...
