(Reuters) - An earthquake of magnitude 7.1 struck 135 km (85 miles) east of the town of Rabaul, on the eastern tip of Papua New Guinea's island of New Britain, at 3.39 a.m. on Friday, local time (1739 GMT on Thursday), the U.S. Geological Survey said.
Although the quake was under the seabed at a relatively shallow depth of 10 km, the Pacific Tsunami Warning Center said there was no threat of a tsunami.
A quake of magnitude 7.5 struck the rugged highlands of the Papua New Guinea mainland on Feb. 26, killing more than 100 people.

Residents wade through flood waters from Tropical Storm Harvey in Beaumont Place, Houston, Texas, U.S., August 28, 2017. Jonathan Bachman: "It was my first day covering Hurricane Harvey. I only made it 500 yards into Houston when I came across a staging area where ordinary people were conducting water rescues in the Beaumont Place neighbourhood of Houston, TX.ï¿½In addition to the rescues, residents were able to walk against the current down a long road which is seen in the image. At first I went out on a boat with a couple from Louisiana to help and document several rescues. When we got back, I looked down the road and saw an almost perfect line of residents making the long walk to the staging area. I intentionally moved to a position so I could photograph them in a way that would convey the magnitude of this storm. I wanted to communicate that it was a never-ending line of residents struggling to get to safety and it would go on for days. Harvey was a very difficult and emotionally taxing assignment. My first instinct was to put down the camera and help. It is always hard to come to the realisation that I am most helpful when I am taking pictures.ï¿½As an observer of suffering you have to believe that your images can make a difference."
