A 6.0-magnitude earthquake struck Indonesia’s central Sulawesi early Sunday, injuring at least 29 people and damaging buildings, the country’s disaster agency said.

The shallow quake, which hit at a depth of one kilometer (6.2 miles), jolted Poso Regency and was felt in surrounding areas, according to the National Disaster Mitigation Agency (BNPB). Two of the injured are in critical condition and receiving hospital treatment.

Authorities said one church was damaged, while parts of another under renovation collapsed, trapping several people beneath the rubble. Video from Poso showed worshippers singing hymns inside a church when the tremors began. The congregation quickly panicked, with people screaming and rushing for the exits. Another video from a surveillance camera captured shelves rattling and goods falling inside a grocery store.

BNPB said there were no immediate reports of deaths, and no tsunami warnings were issued.

The quake comes a month after a massive 8.8-magnitude earthquake off Russia’s far eastern coast sent tsunami waves across the Pacific, prompting alerts from Japan to Mexico.

Indonesia is frequently rattled by seismic activity as it lies on the Pacific “Ring of Fire,” where tectonic plates collide. One of the deadliest recent disasters was in 2022, when a shallow 5.6-magnitude quake killed more than 600 people in Cianjur, West Java, injuring thousands and destroying tens of thousands of homes.
