Tsunami warnings for Bougainville, Papua New Guinea and Solomon Islands have been lifted after a magnitude 7 earthquake on Thursday evening.
The quake, with a shallow depth of 12 kilometres, struck 150 kilometres southwest of the Bougainville town of Arawa.
This evening's quake is the latest in a series of strong shakes to hit the region in recent days.
The Pacific Tsunami Warning Centre says people in the area surrounding the epicentre should exercise caution near the sea as minor fluctuations in level are still possible.
