Pictures taken of sites hit by Friday's tremor and the huge wave that engulfed Palu in Sulawesi show the extent of the damage.
Among the buildings flattened by the shallow 7.5 magnitude earthquake was the Roa Roa Hotel, a cheap hotel that was popular with Indonesian travellers.
The Palu River Bridge was at the entrance to the Palu River, a major watercourse that ran right through the centre of the badly hit town of Palu.
The Apung Mosque was a popular beauty spot but is now isolated after the bridge allowing worshippers to reach it from the shore was destroyed.
The roof of the Baiturrahman Mosque, about 150m from the beach, collapsed into its main prayer room, leaving its newly constructed minaret standing.
Images of the Islamic University, which is also on the seafront, show debris piled up and the entrance and buildings around it wrecked.
Images taken from space show the shifted sands of the bay around Palu and significant areas under water.
