A powerful 7.5-magnitude earthquake hit Indonesia's Sulawesi island at 10:02 GMT on Friday at a depth of 10 kilometers, causing a tsunami up to 2 meters high, the disaster agency said.
"A tsunami has happened in Palu," said Rahmat Triyono, head of the agency's earthquake and tsunami division, referring to Palu, a chartered city on the Indonesian island of Sulawesi.
The tsunami occurred after the tsunami warning was lifted by the country's national disaster agency.
The United States Geological Survey (USGS) first put the scale at 7.7-magnitude but later revised it to 7.5.
This quake happened hours after another 6.1-magnitude earthquake hit the same island, where one person was killed and at least 10 others injured, some houses were also destroyed.
At least three aftershocks happened following the 7.5-magnitude quake within one hour, scaled at 5.8, 5.8, and 5.7 respectively.
There have been no immediate reports of deaths or injuries yet.
Indonesia is prone to quakes as it lies on a vulnerable quake-affected area popularly known as "the Pacific Ring of Fire."
