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 ...
The Cascadia Subduction Zone isn't shutting down—but it's more complicated than previously thought
Recent seismic imaging off Vancouver Island has revealed something extraordinary: a tear in the subducting oceanic plate beneath the Cascadia Subduction Zone. The finding briefly raised the public's ...
Jessica DePaolis (second from left) and the team of researchers studied and compared sedimentary core samples in Montague Island, Alaska, and found evidence that four of the past eight earthquakes ...
Subduction zones represent the most vigorous sites of plate recycling on Earth, where dense oceanic lithosphere sinks into the mantle under the force of its own negative buoyancy. The interplay ...
Earthquakes occur along fault lines between continental plates, where one plate is diving beneath another. Pressure builds between each plate, called fault stress. When this stress builds enough to ...
(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 ...
