Rescue workers are hunting for survivors after a powerful earthquake hit the Indonesian island of Sulawesi and triggered a tsunami, killing at least 384 people. After the 7.5-magnitude earthquake hit on Friday, 28 September 2018, water smashed into buildings and swept away homes in the coastal city of Palu city, home to 350,000 people. More than 540 people are being treated in several local hospitals amid the massive destruction in Palu and 29 people are missing. The death toll could climb in the coming days, Disaster Management Agency, BNPB, spokesman Sutopo Purwo Nugroho warned at a briefing in Jakarta. Electricity and communications have been cut off, making it difficult to assess the damage in Palu and nearby fishing community of Donggala, Sutopo said. “It is not just the people in the large urban areas. There are a lot of people also living in remote communities who are hard to reach” Jan Gelfand, head of the International Red Cross in Indonesia, said. With Palu airport closed, relief workers have to make their way to Palu by road. Sulawesi is one of the biggest islands in the world and the drive from the nearest airport is around 10-12 hours, but what damage there is to the road infrastructure is not yet known. In Palu, authorities are still urging residents to not go inside their homes and sleep away from buildings - in fields, on roads or in yards because of the danger from aftershocks. The horrific scene began Friday when the first in a series of tremors was felt at 3 p.m. (3 am. ET) 35 miles (56 km) north of Palu, according to the United States Geological Survey. Three quakes of 4.9 and larger magnitudes were recorded up to three hours before the tremor near Palu, the USGS said. Hundreds of people had gathered for a festival on the beach in the city of Palu on Friday when waves as high as six metres (18 feet) smashed onshore at dusk. “When the (tsunami) threat arose yesterday, people were still doing their activities on the beach and did not immediately run and they became victims, The tsunami was “about three meters high,” Sutopo Nugroho said. A series of aftershock quakes were reported in the aftermath of the quake, including a 5.8 magnitude tremor just 12 minutes later. An early tsunami warning had been issued by the Indonesian meteorological agency, but was later lifted after the agency ascertained that the water had receded. Indonesia sits on the Pacific Ring of Fire and is regularly hit by earthquakes. In August, a series of major quakes killed more than 500 people in the tourist island of Lombok and destroyed dozens of villages along its northern coast. Palu was hit by a tsunami in 1927 and 1968, according to the BNPB.
