The surface expression of subduction zones are arc-trench complexes. On the ocean side of the complex, where the subducting plate first approaches the subduction zone, there is often an outer trench high or outer trench swell. Here the plate shallows slightly before plunging downwards, as a consequence of the rigidity of the plate. The point where the slab begins to plunge downwards is marked by an oceanic trench. Oceanic trenches are the deepest parts of the ocean floor. WebSubduction probably occurs to a depth of at least 670 kilometers (400 miles), at which point the plate probably becomes plastic. Andesitic volcanism often forms a curved chain of islands, or island arc, that develops between the oceanic trench and … midland low income housing
