PAPUA New Guinea was rocked by 6.8 magnitude earthquake early this morning, just hours after after a 7.2 quake struck off the country's northeast coast.
The US Geological Survey reported the 6.8 quake occurred near the town of Kandrian, on the island of New Britain, at 6.30am.
It hit 30km northeast of the town, at a depth of 62km.
A report on the Geoscience Australia website says the quake could have caused damage up to 60km away and could have been felt up to 757km away.
Two hours before, a 7.2 magnitude quake struck off the coast of the island of New Ireland.
No tsunami warning was issued.
