WebJan 25, 2024 · It is well established that fluid-rock reactions, pore fluid pressure, and fluid flow have a profound effect on fault mechanics and the transition to seismogenic behavior within subduction zones (1–4).Pore fluid pressure along the megathrust in subduction zones is regulated by the balance between fluid sources (inputs) and fluid flow (outputs). Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at convergent boundaries.
