Magnitude 5.7 Earthquake in Papua Province, Indonesia.

The United States Geological Survey recorded a Magnitude 5.7 Earthquake at a depth of 28.43 km, in the Van Rees Mountains of Papua Province, Indonesia, slightly after 4.20 pm local time (slightly after 7.20 am GMT) on Sunday 28 August 2016.An Earthquake of this size has the potential to cause considerable damage, however the area where it occurred is very remote and there are no reports of any damage or casualties at this time.

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.
