Tsunami warning issued for parts of Pacific after earthquake

The magnitude-7.7 earthquake struck Monday at a depth of 65 kilometers (40 miles), about 50 kilometers (30 miles) southeast of the town of Kokopo in northeastern Papua New Guinea, the U.S. Geological Survey said.

The tsunami warning center said tsunami waves reaching 1 to 3 meters (3 to 10 feet) were possible for Papua New Guinea's coastlines.
