A magnitude-6.7 earthquake struck the Indonesian island of Sulawesi on Tuesday, the US Geological Survey (USGS) and the German Research Centre for Geosciences (GFZ) said.
The quake occurred at 11:27 am (0327 GMT) at a relatively shallow depth of 10 kilometres near the city of Palu in central Sulawesi.
There were no immediate reports of damage or injuries. No tsunami warning was issued.
Sulawesi, located between Borneo and Papua New Guinea, is one of the larger islands in Indonesia, a South-East Asian nation made up of more than 17,000 islands.
Indonesia lies in the Pacific Ring of Fire, the world's most geologically active zone, where earthquakes and volcanic eruptions occur regularly.
