Rescue officials feared the full scale of Indonesia's earthquake and tsunami could climb far past the more than 800 already confirmed dead, as several large coastal towns remained cut off Sunday by damaged roads and downed communication lines.
The country's disaster agency said the death toll more than doubled to 832, and nearly all of those were from the hard-hit city of Palu on the island of Sulawesi. The regencies of Donggala, Sigi and Parigi Moutong — with combined populations of 1.2 million — had yet to be fully assessed.
"The death toll is believed to be still increasing since many bodies were still under the wreckage, while many have not been reached," said agency spokesman Sutopo Purwo Nugroho. He said a mass burial would be held Sunday for health reasons.
Bodies covered in blue and yellow tarps lined the streets of Palu, while rescuers dug through rubble in the hopes of finding survivors from the twin disasters that struck Friday evening. There was particular focus on the eight-story Roa-Roa Hotel, where voices from underneath the rubble could be heard calling out for help on Saturday.
The cries from beneath the hotel, which appeared to have toppled over with its walls splintered like pickup sticks, had gone silent by Sunday afternoon. Officials had estimated some 50 people could be inside.
"We are trying our best. Time is so important here to save people," said Muhammad Syaugi, head of the national search and rescue team. "Heavy equipment is on the way."
Metro TV showed about a dozen rescuers in orange jumpsuits climbing over debris with a stretcher carrying the body of a victim from the modest business hotel.
Aid and supplies were being sent to the area via military and commercial aircraft, including helicopters, to reach badly affected areas. Officials said the area was lacking medical supplies, fuel, fresh water and experts.
Indonesian President Joko "Jokowi" Widodo toured Palu on Sunday.
"There are many challenges," Jokowi said. "We have to do many things soon, but conditions do not allow us to do so."
Nugroho said 61 foreigners were in Palu at the time of the disaster. Most of them had been accounted for, but one South Korean was believed to be trapped in the ruins of the Roa-Roa Hotel, while three others from France and one from Malaysia were missing. The survivors were to be evacuated to the Sulawesi city of Makassar in the island's far south.
It's the latest natural disaster to hit Indonesia, which is frequently struck by earthquakes, volcanic eruptions and tsunamis because of its location on the "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin. In December 2004, a massive magnitude 9.1 earthquake off Sumatra island in western Indonesia triggered a tsunami that killed 230,000 people in a dozen countries. Last month, a powerful quake on the island of Lombok killed 505 people.
In Donggala, the site closest to the earthquake's epicenter, aerial footage aired on Metro TV showed the sugary blond sands of beaches swept out to sea, as were some buildings. Damage to some buildings in the town was severe, with plywood walls shredded and chunks of concrete scattered on the pavement. Much of the damage, however, appeared limited to the waterfront.
Palu, which has more than 380,000 people, was strewn with debris from the earthquake and tsunami. A mosque heavily damaged by the quake was half submerged and a shopping mall was reduced to a crumpled hulk. A large bridge with yellow arches had collapsed.
The city is built around a narrow bay that apparently magnified the force of the tsunami waters as they raced into the tight inlet. Nugroho said waves were reported as high as 6 meters (20 feet) in some places.
Looters were stealing from the badly damaged shopping mall, which was not being guarded Sunday. They did not appear to be concerned about their safety, despite ongoing aftershocks and the structure's questionable stability. Residents were also seen returning to their destroyed homes, picking through waterlogged belongings, trying to salvage anything they could find.
Hundreds of people were injured and hospitals, damaged by the magnitude 7.5 quake, were overwhelmed.
Some of the injured, including Dwi Haris, who suffered a broken back and shoulder, rested outside Palu's Army Hospital, where patients were being treated outdoors due to continuing strong aftershocks. Tears filled his eyes as he recounted feeling the violent earthquake shake the fifth-floor hotel room he shared with his wife and daughter.
"There was no time to save ourselves. I was squeezed into the ruins of the wall, I think," said Haris, adding that his family was in town for a wedding. "I heard my wife cry for help, but then silence. I don't know what happened to her and my child. I hope they are safe."
Nina, a 23-year-old woman who goes by one name, was working not far from the beach when the quake hit. She said the quake destroyed her workplace, but she managed to escape and quickly went home to get her mother and younger brother.
"We tried to find shelter, but then I heard people shouting, 'Water! Water!'" she recalled, crying. "The three of us ran, but got separated. Now I don't know where my mother and brother are."
Communications with the area were difficult because power and telecommunications were cut, hampering search and rescue efforts. Most people slept outdoors, fearing strong aftershocks.
Indonesia is a vast archipelago of more than 17,000 islands that span a distance that would stretch from New York to London. It is home to 260 million people. Roads and infrastructure are poor in many areas, making access difficult in the best of conditions.
The disaster agency has said that essential aircraft can land at Palu's airport, though AirNav, which oversees aircraft navigation, said the runway was cracked and the control tower damaged.
AirNav said one of its air traffic controllers, aged 21, died in the quake after staying in the tower to ensure a flight he'd just cleared for departure got airborne safely. It did.
More than half of the 560 inmates in a Palu prison fled after its walls collapsed during the quake, said its warden, Adhi Yan Ricoh. Ricoh said there was no immediate plan to search for the inmates because the prison staff and police were consumed with the search and rescue effort.
Sulawesi has a history of religious tensions between Muslims and Christians, with violent riots erupting in the town of Poso, not far from Palu, two decades ago. Indonesia is the world's most populous Muslim country.
