The strike of most of the elongated structures related to plate bending accompanied by subduction of the Pacific plate is N70°E and is not parallel to the trench axis. The bending-related structures were formed by reactivation of seafloor spreading fabric. Challenger Deep consists of three en echelon depressions along the trench axis, each of which is 6-10km long, about 2km wide, and deeper than 10,850m. The eastern depression is the deepest, with a depth of 10,920±5m.
