The tectonic situation underlying Papua Province is complex, with the island being made up of a number of small tectonic plates being squeezed between the larger Pacific and Australian plates. The area affected by the 6 April quake lies on the boundary between the Maoke Plate, which underlies much of Papua Province and the Woodlark Plate, which underlies much of the east of the island. Other parts of the island lie on the Bird's Head, Australian and South Bismarck Plates. To the north of Papua Province the Caroline Plate is being subducted in the Manus Trench, which is parallel to the northern shore of the island.
