At least 832 people are confirmed to have died but that figure is expected to rise sharply as more remote areas are reached.
The authorities have said they will begin burying victims in mass graves, fearing disease could begin spread. Dozens of people are thought to be trapped alive under the rubble. In Palu, rescuers are awaiting heavy machinery to search the ruins of a hotel and a shopping centre as aftershocks made it unsafe for them to go in. "Communication is limited, heavy machinery is limited… it's not enough for the numbers of buildings that collapsed," said Sutopo Purwo Nugroho, spokesman for the National Disaster Mitigation Agency.
A tsunami warning had been issued after the magnitude 7.5 earthquake hit on Friday, but it is unclear whether it was still in place when the waves hit.
