Summary The outer topographic rise seaward of many island arcs can be explained in terms of a bending moment applied to the oceanic lithosphere either by the downgoing slab to which it is attached or by modest shear stresses acting along the underthrusting plate boundary. The existence of the outer rise does not require large horizontal compressive stresses to maintain it.
