Earthquake strikes near Papua New Guinea - USGS
There were no immediate reports of damages or casualties, and no tsunami warning was in effect.
The latest quake was centred 155 km (96 miles) south of the city of Rabual at a depth of 68 km (42 miles), the USGS said, revising down its initial 6.1 magnitude estimate.
Two stronger earthquakes hit the same area late last week.
