A strong 6.6-magnitude earthquake struck off Papua New Guinea’s Bougainville Island on Saturday but there was no risk of a widespread tsunami, seismologists said.
The quake, scaled back from an initial reported magnitude of 6.9, hit at 0104 GMT and was centred 59 කිලෝ මීටර් (36 සැතපුම්) southwest of the town of Panguna on Bougainville at a depth of 24 කිලෝ මීටර්, මෙම US Geological Survey පවසයි.
In its initial estimate the USGS said there was a low likelihood of casualties and damage.
According to the Hawaii-based Pacific Tsunami Warning Center there was no threat of a destructive widespread tsunami based on historical data.
Geoscience Australia measured the quake at magnitude 7.0 and said it was probably felt within a wide radius, with the potential for localised shaking damage.
“Because it’s such a large event there’s a possibility of damage in that area,” seismologist Emma Mathews told ඒඑෆ්පී.
“But it’s nothing out of the ordinary for such an earthquake-prone country.”
Mathews said it was the latest in a recent cluster of earthquakes in the Panguna region, with five events recorded in the past week including powerful magnitude 7.6 සහ 7.5 tremors that triggered a local tsunami alert.
Those jolts were felt locally but there were no reports of significant damage from remote and isolated Bougainville, which sits between the island of New Guinea and the Solomons.
The rumblings sparked panic in the Solomons capital Honiara, reeling from floods earlier this month that claimed at least 21 lives.
“This is quite an active area, an active tectonic area that receives a high frequency of earthquake activity,” Mathews said.
Quakes of such magnitude are common in PNG, which sits on the so-called Pacific “ගිනි වලල්ලක්”, a hotspot for seismic activity due to friction between tectonic plates.

Last year in February the remote town of Lata in the Solomons was hit by a devastating tsunami after an 8.0-magnitude earthquake. The tsunami left at least 10 people dead, destroyed hundreds of homes and left thousands of people homeless.
