A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific ...

A research team utilized teleseismic double-difference tomography technology to uncover the morphological changes of the Pacific subducting slab in the mantle transition zone beneath Northeast China.

Subduction zone volcanism is driven by the descent of oceanic lithosphere into the mantle, where increasing pressure and temperature liberate volatiles that flux the overlying mantle wedge and induce ...

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 ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

Subduction zones are fundamental engines of plate tectonics, where oceanic lithosphere descends into the mantle, driving seismicity, magmatism and crustal recycling. The interaction of a subducting ...

Researchers recently discovered a huge chain of extinct volcanoes buried deep below South China that formed when two tectonic ...

Deadly car-motorcycle crash shuts down part of Southwest Scholls Ferry Road Monday afternoon, Washington County deputies say. Closure at SW Hillsboro Hwy 219 and Scholls Sherwood and Seiffert; delays ...

Mount Etna is like no other volcano on Earth, new research finds. In fact, the volcano may have formed in a bizarre way, reminiscent of how some seamounts, called petit-spot volcanoes, grow on the ...

A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth’s tectonic history than previously known. Along the Aleutian Arc, the Pacific ...
