A magnitude-6.2 earthquake that shook Indonesia’s Sulawesi island in the early hours of Friday killed at least 37 people and injured hundreds, the country’s disaster mitigation agency said, as tens of thousands of residents fled to safety. The quake was centred 36km south of the Mamuju district in West Sulawesi province, at a depth of 18km, the US Geological Survey said. It was felt strongly for about seven seconds just past 1am. Officials from the Meteorology and Geophysics Agency warned of a potential tsunami if more strong quakes hit Sulawesi. “The latest information we have is that 26 people are dead... in Mamuju city,” said Ali Rahman, head of the local disaster mitigation agency, adding “that number could grow”. “Many of the dead are buried under rubble,” he said. Separately, the national disaster agency said at least eight people had died in Majene, a district south of Mamuju, bringing the total death toll to 37. Rescuers were searching for more than a dozen patients and staff trapped beneath the rubble of the levelled Mamuju hospital. “The hospital is flattened – it collapsed. There are patients and hospital employees trapped under the rubble and we’re now trying to reach them,” said Arianto from the rescue agency in Mamuju city, who goes by one name. At least 62 houses, a public health centre and a military office were damaged in Mamuju, said Raditya Jati, the National Disaster Mitigation Agency’s spokesperson. Landslides were set off in three locations and blocked a main road connecting Mamuju to the Majene district, he said, adding that the agency was still collecting data from areas struck by the quake. In Majene, at least 218 people were injured, as more than 300 houses and buildings were damaged, including health clinics, hotels and offices, the district’s disaster agency chief Sirajuddin said. He said some 10,000 people are now in several temporary shelters. The quake did not trigger a tsunami warning, but the head of Indonesia’s Meteorology and Geophysics Agency, Dwikorita Karnawati, told a news conference that strong aftershocks could follow, with a possibility that another powerful quake could trigger a tsunami. There had been at least 26 aftershocks in the area in the past day, he said. In a video released by the National Disaster Mitigation Agency, a girl trapped in the wreckage of a house cried out for help and said her mother was alive but unable to move out. “Please help me,” the girl told rescuers, who replied that they desperately wanted to help her. In the video, the rescuers said an excavator was needed to save them. Other images in the video showed a severed bridge and damaged and even flattened houses.

On social media, videos showed residents fleeing to higher ground on motorcycles, and a child trapped under the rubble as people tried to remove debris with their bare hands. On Thursday, a magnitude-5.9 quake hit under the sea in the same region, damaging several homes but causing no apparent casualties.

In 2018, a devastating 6.2-magnitude quake and subsequent tsunami struck the city of Palu , in Sulawesi, killing thousands of people. A powerful Indian Ocean quake and tsunami in 2004 killed 230,000 people in a dozen countries, most of them in Indonesia. Additional reporting by Agence France-Presse, Associated Press and Reuters
