Manus Trench is a trench delineating the oceanic boundary between the Caroline Plate and North Bismarck Plates, in Papua New Guinea.[1] The Kilinailai Trench, which looks as if it is a continuation of the Manus Trench, marks the boundary between the Pacific and North Bismarck Plates. Perpendicular to the two trenches is another trench, the Mussau Trench separating the Caroline Plate and Pacific Plate.
