Iran Press/Asia: Hundreds had gathered for a festival on the beach of the city of Palu on Friday when waves up to six meters (18 feet) high smashed ashore just on dusk, sweeping many to their death and destroying anything in their path,Reuters reported.
"When the (tsunami) threat arose yesterday, people were still doing their activities on the beach and did not immediately run and they became victims," Sutopo Purwo Nugroho, spokesman of Indonesia's disaster mitigation agency BNPB said in news briefing in Jakarta.
"The tsunami didn't come by itself, it dragged cars, logs, houses, it hit everything on land," Nugroho said.
Some people climbed six metre (18 feet) trees to escape the tsunami and survived, he said.
Strong aftershocks continued to rock the coastal city on Saturday morning following the massive 7.5 magnitude earthquake on Friday, which triggered the tsunami.
Bodies of some victims were found trapped under the rubble of collapsed buildings, he said, adding 540 people were injured and 29 missing. Dozens of injured people were being treated inmakeshift medical tents set up outdoors, TV images showed.
Photos confirmed by authorities showed bodies being lined up along the street on Saturday, some in bags and some with their faces covered with clothes.
Indonesia's meteorological and geophysics agency BMKG issued a tsunami warning after the quake, but lifted it 34 minutes later. The agency has been widely criticized for not informing atsunami had hit Palu on Saturday, though officials said waves had come within the time the warning was issued.
The quake and tsunami caused a major power outage that cut communications around Palu and on Saturday authorities were still having difficulties coordinating rescue efforts.
More than 600,000 people live in Donggala and Palu. Chief security minister Wiranto told TVOne the military had started sending in cargo planes from the capital Jakarta carrying relief aid.
The city's airport is slated to reopen on Saturday afternoon after being closed as its runway and air traffic control tower was damaged in the quake, authorities said.
President Joko Widodo is scheduled to visit evacuation centers in Palu on Sunday.
The Palu area was hit by a less powerful quake earlier on Friday, which destroyed some houses, killed one person and injured at least 10 in Donggala, authorities said.
The US Geological Survey put the magnitude of the second quake at a strong 7.5, after first saying it was 7.7.
