A powerful 6.3 magnitude earthquake struck the highlands of Papua New Guinea on Saturday, the U.S. Geological Survey (USGS) said, as the region struggles to recover from a massive 7.5 quake only two months ago.

There were no immediate reports of damage or injury.

The quake was 82 kms southwest of Porgera in Enga province and 47 kms deep, said the USGS. Earlier European quake monitor EMSC reported it at 6.5 magnitude and only two kms deep, but later scaled it down.

The earthquake happened just two months after a 7.5 quake struck the same highlands area, killing 125 people and leaving hundreds of thousands of people homeless.
