Cornell-led researchers drilled 7 km deep into the Japan Trench to study the fault behind the 2011 Tohoku earthquake, ...

(a) Tectonic setting background in the Tonga-Lau-Fiji region. (b) Schematic diagram of the upper mantle structure beneath the Tonga-Lau-Fiji region. A landmark study published in Geoscience—a ...

What's at the bottom of the Mariana Trench, and how do we know? How deep does the ocean go? We'll answer these questions and more in this deep dive into the world's oceans. Come on in: The water's ...

Scientists have mapped the deep forces at play beneath the Tonga Subduction Zone, exposing how mantle plumes, subducting slabs, and tectonic shifts fuel volcanic activity and plate motion.

Any self-respecting convenience store, or konbini in Japan, is guaranteed to stock tamago sandos: the country’s beloved egg sandwich. The closest comparison in the West would be classic egg ...

Earth’s surface is constantly shifting, shaped by the slow but powerful movement of tectonic plates. While some plates have persisted for hundreds of millions of years, others have vanished ...

The deep sea is littered with all the junk we carelessly toss away, from plastic bags to old washing machines to incredibly creepy figurines. Not even the greatest depths of the ocean are spared ...

Dominated by silicate-rich minerals with high iron and magnesium content the mantle is predominantly solid but behaves as a viscous flow that creeps with geodynamic timescale. This movement drives ...
