Marianas Trench The oceanic trench which marks the destructive margin between the Pacific Plates and Philippine Plates. The trench is about 11 km deep, and there is evidence of little or no accretionary wedge. The subduction zone steepens at depth, becoming almost vertical, with hypocentres down to approximately 700 km.
