Indonesian President Joko Widodo has said all of the victims of the 7.5 magnitude quake and tsunami that struck the west coast of Sulawesi island on September 28, killing more than 1,600 people, must be found.
The official death toll from the quake and the tsunami it triggered has risen to 1,649, but will certainly increase.
Bodies are still being recovered from the ruins of buildings in the small city of Palu and from neighborhoods hit by liquefaction, a phenomenon that turns the ground into a roiling quagmire, in the south of city.
"We're going to clear off all the superficial rubble that's on top and get into the spaces and see if there are bodies", Allibert told Reuters as he surveyed a terrible jumble of debris.
"We've marked the possible bodies with sticks".

Min Kapala, a 49-year-old teacher, said she came to the city of more than 25 churches from an outlying area because her usual house of worship was destroyed and liquefaction moved a different piece of ground to its location.
Mr Allibert said it would take months to find all the bodies.
"[The survivors] can not stay for very long in the displaced persons camps because [the children] must return to school soon", BNPB spokesman Sutopo Purwo Nugroho said at a press conference on Sunday, adding that emergency schools may be set up using tents. "Where are they? What if they are still alive?"
"We have vaccinated our teams, but we need to be extra cautious as they are exposed to health hazards". Eight victims in black body bags were arranged in a row at the crumpled neighbourhood of Balaroa, destined for a mass grave. One man, Nizar, said he had identified six relatives among them.
