Magnitude 7.2 quake strikes off Papua New Guinea

A 7.2 magnitude earthquake struck in the Pacific between Papua New Guinea and the Solomon Islands on Thursday, with hazardous tsunami waves possible along the coast, seismologists said.

The quake hit at a depth of 22 kilometres some 149 kilometres southwest of Panguna in PNG and 642 kilometres from the Solomons capital Honiara, the US Geological Survey said.

The Pacific Tsunami Warning Center said no Pacific-wide threat was expected but “hazardous waves are possible within 300 kilometres of the epicentre along the coasts of the Solomon Islands and Papua New Guinea”.

“There is a warning out for a local tsunami,” Geoscience Australia senior seismologist Jonathan Bathgate told AFP, but added that no serious damage to nearby communities was expected.

“The coastlines there are sparsely populated, so we do tend to find that even if there’s a small tsunami, it largely goes unnoticed. “But there is still a need for the people on Bougainville and the surrounding islands to certainly move away from the coastline until this threat has passed.” 

Chris McKee, from the PNG Geophysical Observatory in Port Moresby, echoed similar sentiments.

“It may have generated a tsunami, we’re not certain yet,” he said. “We have put out a tsunami warning to the provinces in the area, warning people to be aware.

“We’re not sure at the moment whether there has been any damage but it was a long way off the coast,” he added. The area around Papua New Guinea has been rattled by a series of quakes over the past week, including a 7.4 magnitude tremor on Tuesday.
