Shaking from the powerful undersea quake wrecked a church and dozens of homes around the city.
“I ran out of my house with my kids as soon as I felt the tremors,” said Pinta Uli, a mother of two, who also told The Associated Press that she saw one street lamp topple to the ground.
A landslide triggered by the quake heavily damaged the main road that connects Manokwari with regions to the south.
The Tempo daily reports that hundreds of residents set up emergency tents outside their damaged homes.
While no tsunami warning was issued, some residents fled to higher ground immediately after the quake struck at 8:15 a.m. local time.
Despite the damage, there were no reports of injuries or fatalities.
