The offshore quake hit at 5:38 am (1938 GMT Monday) and occurred 128 kilometres (80 miles) southeast of Lorengau, Papua New Guinea, according to the US Geological Survey (USGS).

The epicentre was at a depth of 6.6 kilometres.

No damage or injuries were immediately reported. The Hawaii-based Pacific Tsunami Warning Center said there was no threat of a widespread tsunami.

Quakes are common for the island nation that lies on the 4,000-kilometre-long Pacific Australia plate, which forms part of the "Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.
