USGS and EMSC registered shallow M 6.8 struck near coast of New Guinea, Papua New Guinea on April 16, 2013 at 22:55 UTC. The epicenter was 136 km (84 miles) WNW from Wewak and 870 km (5441 miles) NW from Port Moresby, Papua New Guinea at coordinates 3.178°S, 142.514°E. The depth of epicenter was 8 km (5 miles). There is no reports of damage. No tsunami warning was issued.
USGS has calculated that some coastal settlements may experience a MMI VIII Severe shaking. These data are based on a M6.8 Magnitude at an extremely shallow depth of 8 km. The MMI VIII shaking may also be a problem for concrete houses near the coast. PNG houses are often struck by very strong to massive earthquakes but mostly the earthquake data are more favorable. GDACS has calculated that the max. tsunami wave could be 30 cm. Pacific Tsunami Warning Center didn't issue tsunami warning or tsunami watch alert.
