A major 7.9-magnitude earthquake struck Papua New Guinea Sunday, but a tsunami alert initially issued for the Pacific island nation and its neighbors was later canceled.
The tremor struck 40 kilometers (25 miles) west of Panguna on Papua New Guinea's Bougainville island at a depth of 153 kilometers at 330 pm local time (0430 GMT), the US Geological Survey said.
Its preliminary assessment added that light to moderate damage was possible on Bougainville island. The quake was revised down from 8.0-magnitude to 7.9.
The Pacific Tsunami Warning Center said waves of between 0.3 and one meter (1-3 feet) above tide level were possible for some coastal areas of PNG and the neighboring Solomon Islands.
The center issued another statement about an hour later to say that threat has now passed.Even though it is quite deep at 150 kilometers, because it is such a large earthquake, it will produce shaking on the surface, Geoscience Australia seismologist Spiro Spiliopoulos told AFP.
He added that some damage was possible. Aid group Save the Children has an office on Buka island next to the main Bougainville island. Its PNG country director Jennifer El-Sibai described the quake as really powerful but said no reports of damage had been received so far.
Connie Wihongi-Stevens posted on Facebook that her husband, who is working in Arawa some 46 kilometers west of where the quake struck, was safe but shaken by the tremor.
