A magnitude 6.7 earthquake struck northeastern Papua New Guinea on Saturday.
According to the United States Geological Survey, no causalities or damages were reported immediately.
The strong quake had a depth of 53 kilometres (33 miles) and hit at around 7:30 pm (0830 GMT) with the epicentre about 56 kilometres southeast of the coastal town of Madang, reports AFP.
An aftershock of equal magnitude hit off the coast of Madang minutes later.
Earthquakes are common in Papua New Guinea, but rarely cause widespread damage.
Outside major towns and cities, most areas are sparsely populated, and what buildings there are tend to be made of wood.
But some quakes are more destructive.
