Sydney:
A strong 6.6-magnitude earthquake struck off Papua New Guinea in the Solomon Sea early on Saturday, US geologists said.
The offshore quake hit at 1:00 am (1500 GMT Friday) and occurred 193 kilometres (119 miles) south of Taron on PNG, according to the US Geological Survey (USGS).
The epicentre was at a depth of only 10 kilometres.
The Pacific Tsunami Warning Center said there was no threat of a widespread tsunami but cautioned that local tsunamis have been generated by earthquakes of similar size in the past.
Quakes are common in PNG, which sits on the so-called Pacific "Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.
