Medical team members help patients outside a hospital after an quake and a tsunami hit Palu, on Sulawesi island.
Authorities were having difficulties coordinating rescue efforts as the 7.5 magnitude quake caused a power outage that cut communications around Palu and the nearby fishing town of Donggala, the closest to the epicentre of the quake 27 km (17 miles) away.
In Palu, the capital of Central Sulawesi province, the city of more than 380,000 people was strewn with debris from collapsed buildings.
On Friday night, Indonesia's president said he had instructed the security minister to coordinate the government's response to the quake and tsunami.
"We are receiving reports of widespread damage to buildings because of the natural disaster".
The chief of the meteorology and geophysics agency, Dwikorita Karnawati, said the tsunami waves were up to three metres high.More news: Brett Kavanaugh FBI Investigation Won't Matter: Democrats have their minds made up
"I just ran when I saw the waves hitting homes on the coastline", said Palu resident Rusidanto, who like many Indonesians goes by one name.
In December 2004, a massive magnitude 9.1 quake off Sumatra in western Indonesia triggered a tsunami that killed 230,000 people in a dozen countries.
An official with the local disaster agency, Akris, said "many houses have collapsed".
Earlier this year, a series of powerful quakes hit Lombok, killing more than 550 people on the holiday island and neighbouring Sumbawa.
Indonesia is prone to earthquakes because of its location on the "Ring of Fire", an arc of volcanoes and fault lines in the Pacific Basin.
The disaster was the world's 3rd biggest quake since 1900, and lifted the ocean floor in some places by 15 meters.More news: U.S. takes 3-1 lead after first session of Ryder Cup
