Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme pressure and heat ...

Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

Our planet's interior is much too deep and hot to explore with probes, so scientists rely on seismic waves to understand and model its structure. Seismic waves are shock waves tha ...

Seismic imaging has revealed two colossal regions deep within Earth’s mantle that could reshape our understanding of the planet's composition and history. These continent-sized anomalies, known as ...

Many geologists attribute the great variation in the temperature gradient to complex irregularities in the structure of the earth's crust. Some even maintain that the interior of the earth is cold ...

Potential patches of Earth's ancient crust, sometimes called "sunken worlds," may have just been discovered deep within the mantle, thanks to a new way of mapping the inside of our planet.

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found lurking below Africa and the Pacific Ocean, entombed some 1,200 miles below the ...

Scientists have discovered massive structures deep inside Earth, beneath Africa and the Pacific Ocean. These structures are ...

This discovery was made possible through a groundbreaking technique that maps seismic waves traveling through the Earth's ...

A record-breaking deep earthquake registered in May 2015 offshore of Japan likely was not a tectonic event but triggered by a ...
