Geologists have uncovered the remains of a massive tectonic plate beneath the Pacific Ocean, a plate that had been hidden for ...

Our planet has been asteroid-smashed, melted and eroded, enough that most of its original armor has been long buried. Except ...

Researchers mapped a pulsing mantle plume under Afar that channels molten rock upward, stretching Africa’s crust until it ...

Beneath Ethiopia, the Earth’s mantle is pulsing like a slow, steady heartbeat, slowly tearing Africa apart and laying the ...

Their new research reveals that rhythmic, heartbeat-like pulses of molten rock are rising from deep within the Earth’s mantle ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

Researchers have discovered an unusual plume of magma beneath Oman that may have changed the course of the Indian tectonic plate between 25 million and 40 million years ago.

Caused by intense tectonic activity and plate subduction, this region hosts 75% of the world’s active volcanoes and 90% of its earthquakes. Stretching 40,000 km, it spans countries like Japan ...

There, the tectonic plates moved at around 21 millimetres per year before two major earthquakes struck — one of magnitude 8.0 in 1934 and another of 7.8 in 2015.

There may also be other types of plumes that do not reach the surface—called ghost plumes. They are believed to exert an influence on plate tectonics. Until now, no ghost plumes have been observed.

Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...
