Indonesia disaster response agency has said the death toll has hit 1200 following an earthquake that hit the country on Friday.
The figure stood at 844 before Tuesday morning.
The 7.5-magnitude quake struck just off the central island of Sulawesi, setting off a tsunami that hit the coastal city of Palu.
People there are in dire need of food, fuel and water and there are growing fears that some survivors may still be trapped.
Indonesian Red Cross officials reporting to BBC have said that 34 Indonesian students whose bodies were found under a church buried by a mudslide were among those killed.
They were among a group of 86 students reported missing from a Bible camp in the Jonooge Church Training Centre.
