SYDNEY: A 6.7-magnitude earthquake struck off Papua New Guinea on Wednesday, officials said, but no Pacific-wide tsunami warning was issued. The tremor was estimated at a depth of close to 500 kilometres (around 300 miles) some 900 kilometres northeast of the capital Port Moresby, the United States Geological Survey said. “Based on all available data a destructive Pacific-wide tsunami is not expected,” the Hawaii-based Pacific Tsunami Warning Center said. Australian seismologists estimated the quake, which hit in Papua New Guinea’s eastern New Britain area, at 6.5-magnitude. “It’s only 10 to 20 kilometres off the coast but still it’s very deep, so it wouldn’t be anything extreme at all. No tsunami,” seismologist Jonathan Bathgate told AFP.
