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 ...

(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 initiation marks the birth of a convergent plate boundary, where one tectonic plate begins to descend beneath another into the mantle. This process underpins the global plate-tectonic cycle ...
