The death toll in the devastating quake and tsunami that hit Indonesia's island of Sulawesi increased to 832 on Sunday as rescue workers combed through concrete and lumber searching for survivors, the country's disaster management agency said.
Indonesia's disaster mitigation agency said "many bodies" had been found along the shoreline of the Indonesian city of Palu on Sulawesi island which was hit by a major quake and a tsunami on Friday.
A 25-year-old woman was found alive during the evening in the ruins of the Roa-Roa Hotel, according to the National Search and Rescue Agency, which released photos of the her lying on a stretcher covered in a blanket.
It's also believed that there are individuals trapped under debris. Hundreds of people gathered at the mall searching for loved ones.
Authorities in the city of Palu, located on the Indonesian island Sulawesi, say over 500 people were also injured in the disaster and expects the death toll to rise as at least 29 persons are listed as missing.
On Friday, September 28, the Indonesian Island of Sulawesi was hit by a series of earthquakes, triggering a tsunami as high as three meters.
Rescuers are trying to reach those trapped under collapsed buildings.
The Red Cross said it had heard nothing from the Donggala region.
"To me this is a tragedy for science, even more so a tragedy for the Indonesian people as the residents of Sulawesi are discovering right now", said Louise Comfort, a University of Pittsburgh expert in disaster management who has led the US side of the project, which also involves engineers from the Woods Hole Oceanographic Institute and Indonesian scientists and disaster experts.
Already, a story of bravery has emerged from the tragedy.
However, it was a 7.5 magnitude quake that triggered a tsunami warning.
Indonesia sits on the Pacific Ring of Fire and is regularly hit by earthquakes, including the devastating Boxing Day 2004 quake and tsunami that killed more than 120,000 in northern Aceh province alone.
Even as relief efforts were underway, questions remained about the apparent failure of an early warning system and a tsunami alert that was quickly dropped by the Indonesian geophysics agency. "I can't reach them by phone", she said.
State-owned flight navigation service AirNav Indonesia issued a notification on Friday evening that the airport would be closed for 24 hours, until 7.20 p.m. on Saturday. Reuters was not able to authenticate the footage.
Images showed a double-arched yellow bridge had collapsed with its two metal arches twisted as cars bobbed in the water below.
Around 16,700 people were evacuating to 24 centres in Palu.
The video clip, shot on a smartphone and widely broadcast Saturday on Indonesian TV, showed water swallowing an entire row of buildings and gushing into streets and a damaged mosque as onlookers ran in terror.
President Joko Widodo visited a housing complex that was flattened when the quake liquefied the soil it stood on and called for patience.
"It is horrifying", he told ABC TV's Insiders programme on Sunday.
The national search and rescue agency said one woman was rescued overnight in the neighborhood of Balaroa, near Palu, where houses were swallowed up when the natural disaster caused soil liquefaction.
Indonesia, a vast archipelago of more than 17,000 islands, is prone to earthquakes because of its location on the "Ring of Fire", an arc of volcanoes and fault lines in the Pacific Basin.
