Sydney:
A 5.6-magnitude earthquake struck Papua New Guinea on Tuesday, the US Geological Survey said.
The quake hit 125 kilometres (77 miles) southwest of the town of Panguna on Bougainville Island at 8:00 pm local time (10:00 GMT), at a depth of 10 kilometres.
Strong earthquakes are common in the impoverished country, which sits on the so-called "Pacific Ring of Fire", a hotspot for seismic activity due to friction between tectonic plates.
A giant tsunami in 1998 killed more than 2,000 people near Aitape, on the country's northwest coast.
