Powerful earthquake shakes Papua New Guinea

A powerful earthquake struck waters off Papua New Guinea on Thursday, but there were no immediate reports of injuries or damage.

The U.S. Geological Survey said the 6.7-magnitude quake struck 21 miles (32 kilometers) beneath the ocean floor.

It shook the coastal towns of Kandrian and Kimbe on the island province of New Britain, according to Papua New Guinea's Geophysical Observatory, which noted that both are 40 miles (65 kilometers) or less from the epicenter.

There were no immediate reports of damage or injuries, however.

Papua New Guinea lies on the "Ring of Fire" — an arc of earthquake and volcanic zones that stretches around the Pacific Rim and where about 90 percent of the world's quakes occur.

The Pacific Tsunami Warning Center said there was no threat of a destructive tsunami from the 1:12 p.m. quake given its magnitude.
