The death toll from the earthquake that sent five metre-high tsunami waves travelling at speeds of up to 800kph crashing into the Indonesian island of Sulawesi on Friday evening, has crossed 840.
Indonesian vice-president Jusuf Kalla warned it could reach into the thousands.
Thousands of homes, hotels, shopping malls and several mosques collapsed as the disaster left Sulawesi island devastated. Over 821 fatalities were reported from the city of Palu, with 11 casualties so far recorded in Donggala, the worst-hit area, which is home to 300,000 people. Hundreds of bodies have been found on beaches and authorities fear many may have been washed out to sea.
The bodies are being disposed of in mass graves, the authorities explaining they want to prevent an outbreak of disease caused by decomposing bodies. A BBC report said bodies wrapped in orange, yellow and black body bags were carried in trucks to the grave, dragged into the pit and motorised diggers poured earth on top.
Speaking at a press conference, Sutopo Purwo Nugroho, the spokesman for the BNBP disaster agency, said the area affected was much bigger than originally thought and some remote areas have yet to be contacted.
“Communication is limited, heavy machinery is limited… it’s not enough for the numbers of buildings that collapsed,” said Sutopo Purwo Nugroho, spokesman for the National Disaster Mitigation Agency, according to a BBC report.
Yenni Suryani, of Catholic Relief Services, said aid agencies were struggling to get staff into affected areas as the main airport at Palu was damaged, landslides had cut road links and “power is out almost everywhere”, the report said.
Some survivors have been looting shops for food, water and fuel, telling reporters they have run out of supplies.
Reuters news agency reports that police are escorting aid convoys to prevent supplies being stolen.
President Joko Widodo has welcomed offers of international help.
Several jail breaks reported
Meanwhile, government officials say some 1,200 inmates escaped from three prisons in the region as the quake struck. One prison in tsunami-struck Palu city saw most of its 581 inmates storm past guards and escape to freedom through walls collapsed by the massive 7.5 magnitude shake.
Inmates had fled from another overcapacity facility in Palu by breaking down its main door and another in Donggala, an area also hit by the disaster.
The Donggala jail was set on fire and all 343 inmates were now on the run, Utami said. The arson was thought to have been sparked by angry detainees demanding to see their families. “They panicked after learning that Donggala was badly hit by the earthquake,” Utami said, according to media reports.
The 7.5 magnitude quake, which struck in the early evening, was centered along the coast of the island of Sulawesi about 50 miles north of Palu. The earthquake was powerful but shallow and with more lateral than vertical movement, not typically the kind of tremor that sets off tsunamis.
A sophisticated tsunami warning system was put in place across the whole Pacific region after the 2004 disaster, which killed nearly a quarter of a million people.
A tsunami warning was issued after the earthquake hit on Friday, but many people in Palu did not receive alerts because of power cuts caused by the tremor. There were also no sirens located along the coast.
Indonesia, one of the world’s most disaster-prone countries, lies on the Pacific “Ring of Fire” where tectonic plates collide and many of the world’s volcanic eruptions and earthquakes occur.
