Videos of the aftermath of a 7.6 magnitude quake show cracked roads and damaged buildings.
A 7.6 magnitude earthquake has struck off eastern Papua New Guinea, causing damage to buildings and spreading panic among residents.
The United States Geological Survey said the quake struck at a depth of 61km (38 miles), about 67km (41 miles) from the eastern town of Kainantu on Sunday morning.
It issued a tsunami warning, but subsequently said the threat “has now passed”. But it did, however, note that there could still be “minor sea level fluctuations in some coastal areas”.
There were no immediate reports of casualties.
Papua New Guinea residents took to the social media sharing images and videos of cracked roads, damaged buildings and cars, and items falling off supermarket shelves.
Video of damage to a university in the eastern highland town of Goroka showed large cracks appearing in walls and window awnings falling during the quake.
Locals in Lae and Madang, closest to the epicentre, told the AFP news agency that the shaking was much more vigorous than previous quakes.
“Very strong, everything was like sitting on a sea – just floating,” said Hivi Apokore, a worker at the Jais Aben Resort near Madang.
Earthquakes are common in Papua New Guinea, which sits on the Pacific Ocean’s “Ring of Fire,” a hotspot for seismic activity due to friction between tectonic plates.
A magnitude 7.5 quake rocked the country’s remote mountainous highlands in 2018, killing more 100 people and damaging thousands of homes.
In neighbouring Indonesia in 2004 a 9.1-magnitude quake triggered a tsunami that killed 220,000 throughout the region.
