PAPA NEW GUINEA (CBS SF ) — The U.S. Geological Survey says a strong earthquake has struck in Papua New Guinea, but a tsunami is unlikely.

The USGS says the quake’s epicenter was located 81 miles (131 kilometers) southeast of Kokopo, Papua New Guinea and was at a depth of 37 miles (60 kilometers). The quake hit at 3:45 p.m. PDT Thursday.

There is no tsunami threat from this earthquake, according to NOAA’s Pacific Tsunami Warning Center in Hawaii.

On March 30, a magnitude 7.7 earthquake in Papua New Guinea prompted a tsunami warning. A tsunami of two feet was measured in the harbor of Rabaul, a town near the epicenter of the earthquake. No damage was reported.
