(CNN/PIX11) — A magnitude 7.7 earthquake has struck off Papua New Guinea, the U.S. Geological Survey said Sunday.
The quake was 40.8 miles (65.7 km) deep, the USGS said. Its epicenter was 54 km (34 km) southeast of Kokopo, Papua New Guinea.
The Pacific Tsunami Warning Center said a destructive Pacific-wide tsunami is not expected, but hazardous tsunami waves are possible within 621 miles (1,000 km) of the epicenter along the coasts of Papua New Guinea and the Solomon Islands.
Wave size could range from 3 to 10 feet along the Papua New Guinea coastlines.
There have been no immediate reports of injuries or the extent of the damage.
