Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the planet’s ...

"It’s sort of a mystery in terms of fundamental physics." The post Scientists Investigate Strange Rumbling Beneath Utah ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

Scientists have confirmed that a mysterious Utah earthquake first detected in 1979 really did occur nearly 90 kilometers ...

American seismologists have confirmed the existence of a rare class of seismic events — earthquakes in the Earth's upper ...

Scientists have confirmed a rare “impossible” earthquake deep beneath Utah, revealing a hidden source of seismic activity ...

The upper mantle plays a central role in Earth’s dynamic evolution, acting as both a conveyor of tectonic plates and a reservoir for geochemical processes. Seismologists probe this region using body ...

Somewhere south of India, the ocean surface dips by roughly 100 meters below the expected shape of the Earth, a gravitational ...

The Indian-Eurasian continental collision is one of the most spectacular geological events since the Cenozoic, forming the Tibetan Plateau, known as the "roof of the world". The non-uniform ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...
