The Pacific Tsunami Warning Center says there was no tsunami alert issued after a strong earthquake struck off the coast of Papua New Guinea on Monday.
The US Geological Survey says the magnitude-6.5 quake struck 122 kilometers west of Arawa, the capital of Bougainville province, at a depth of 43 kilometers. There were no immediate reports of injuries or damage.
The Pacific Tsunami Warning Center says there was no threat of a destructive, widespread tsunami and that sea-level gauges in the region showed no unusual wave activity.
