A magnitude 6.6 earthquake struck off the east coast of Papua New Guinea this morning, the U.S. Geological Survey said.
The quake struck at a depth of 51 kilometers (32 miles) underwater and about 123 kilometers (76 miles) from the nearest town of Kokopo.
Authorities did not issue a tsunami warning.
Earthquakes are common in Papua New Guinea, which lies on the Pacific Ring of Fire, a zone of intense tectonic activity.
