Muhammad Nur, 27, his wife Nita Puspita, 25 and Nita's sister Widya Wijayanti, 14, stand in front of their former home, obliterated by ground liquefaction looking for useful items, in Petobo neighbourhood, Palu, Central Sulawesi, Indonesia, October 11, 2018. The family was in a light-hearted and happy mood despite their circumstances. Nita described a miracle amid the tragedy: she lost her one-year-old daughter in the earthquake only to find her again at a shelter three days later. The child had been found and rescued by a neighbour. "When we saw the ground moving, we just started running. I saw the asphalt rising. I was carrying my three-year-old in one arm and holding my seven-year-old sister in the other hand. I was running and I was looking for my baby, but I couldn't find her," Nita recalled. "We looked everywhere afterwards, and I was so worried. Finally, someone suggested we looked at one of the shelters nearby and there she was. I was just so relieved and happy to find her."

Wooden beams tilted at crazy angles poke out of piles of shattered concrete littered with battered motorbikes and household items, from crumpled pots and pans to smudged notebooks and soft toys. An earthquake of magnitude 7.5 hit Indonesia's coastal city of Palu. As many as 5,000 people may still be buried under the mud, disaster relief officials estimate. Indonesia called off the search for victims on Friday, two weeks after the quake, citing health concerns, despite residents' pleas to continue. The town in the province of central Sulawesi was among those hardest hit by the phenomenon of ground liquefaction, when the shaking earth turns soft, damp soil into a roiling quagmire, dragging thousands of houses and people under mud and asphalt. The destructive waves of soil smashed thousands of homes, cars and buildings into each other, carrying some of them hundreds of metres from their original position within minutes.
