A powerful earthquake struck Papua New Guinea on Tuesday morning generating a small tsunami near the epicenter.

Officials with the Geophysical Observatory in Port Moresby said that the tsunami was 3 feet high and struck in the harbor of Rabaul.  The tsunami caused no flooding and it did not pass the level of the high tide.

The magnitude 7.5 quake struck around 1:45 a.m. local time.

The quake happened along the tectonic plate under Australia and its overriding Pacific plates.  The quake has been preceded by a series of quakes along the fault line that started with a magnitude 7.5 quake on March 29, 2015.

Local officials say there was no widespread damage because of the quake but power lines were brought down in the area of Rabaul.  In Kokopo, buildings were reported with cracks in the walls and other structural damage but there were no reports of injuries.

The quake site is along the Pacific Ring of Fire.
