The concurrent subduction of the Pacific and Atlantic plates resulted in the formation of a mantle plum and the ascent of magma. Credit: Nicolas Riel Earthquakes and volcanism occur as a result of ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

While it's the reigning theory now, the road to acceptance was long and bumpy for plate tectonics, which describes how large portions of Earth's crust slide, grind, rise and sink ever so slowly across ...

Hidden deep beneath the Pacific Ocean, researchers have uncovered anomalies in the Earth’s mantle that defy existing geological theories. Using advanced seismic imaging, a team of geologists from ETH ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

Geoscientists from the University of Toronto have made a breakthrough discovery that adds new dimensions to the theory of plate tectonics. Their research, published in Geophysical Research Letters, ...

Researchers discovered new undersea faults on the Pacific plate, some of which are thousands of meters below the surface of the ocean and hundreds of kilometers long. Credit: NOAA/NASA GOES Project A ...
