Subduction zone trench migration: Slab drive or overriding-plate-driven?

Schellart, Wouter


Subduction zones on Earth, and their associated trenches and hinges, migrate with respect to the overriding plate, as indicated by overriding plate deformation (e.g. backarc extension or backarc shortening), and migrate with respect to hotspot and no-net-rotation reference frames (global or "absolute" reference frames). Three geodynamic models exist that attempt to explain how "absolute" trench migration velocity correlates with overriding plate deformation. In one model, trench and hinge...[Show more]
