A magnitude 7.6 earthquake shook Papua New Guinea on Sunday, damaging buildings, causing landslides: at least one person died and several others were seriously injured, AFP reported.
Residents in northern towns near the epicenter reported strong tremors.
Member of Parliament Kessy Sawang said that in the remote mountain village of Matoko, one person was buried under a landslide and died, while several others were seriously injured and were airlifted to a hospital.
She said there was serious damage in villages along Finisterre Ridge and in some coastal areas, and she fears more injuries and deaths.
The earthquake was felt even in the capital, Port Moresby, some 480 kilometers away.
The U.S. Geological Survey first issued a tsunami warning for nearby coastal areas, but later said the threat was already over.
According to the U.S. Geological Survey, the quake struck at a depth of 61 kilometers, about 67 kilometers from the city of Cainantu.
In neighboring Indonesia, a 2004 magnitude 9.1 earthquake caused a tsunami that killed 220,000 people across the region, including about 170,000 in Indonesia.
The U.S. Geological Survey also reported two strong earthquakes in the remote Mentawai Islands off the west coast of the Indonesian island of Sumatra.
The magnitude 6.0 earthquake struck at a depth of 20 kilometers at about 6:10 a.m. local time, followed by a magnitude 5.7 quake at a shallower depth of 10 kilometers a few minutes later.
There were no reports of casualties or damage, but the tremors forced residents of the Mentawai Islands to flee to evacuation centers set up last week after another quake.
The earthquake was also felt in the city of Padang, capital of West Sumatra province, where residents fled their homes after tremors shook buildings.
