A strong 6.8-magnitude earthquake struck Papua New Guinea today, the US Geological Survey(USGS) said, around 30 minutes after a similar quake shook the same area.
The second quake hit at 11:35 pm local time (1335 GMT) around 105 kilometres (65 miles) east of Kandrian on New Britain island, USGS said, at a depth of 51 kilometres.
At 1304 GMT, USGS recorded a 6.9-magnitude quake 110 kilometres east of Kandrian, at a depth of 58 kilometres.
The epicentres of both quakes were around 525 kilometres northeast of Papua New Guinea's capital Port Moresby.
The Pacific Tsunami Warning Center said there was no threat of a widespread destructive tsunami from either quake, based on previous earthquake and tsunami data.
