A strong earthquake with a magnitude of 6.6 rocked eastern Indonesia early Thursday, prompting a tsunami alert.
The country's meteorological agency said the tremor was centered 275 kilometers southwest of Maluku province at a depth of 10 kilometers.
The agency said the quake had the potential to cause a tsunami, but later retracted it after no waves were reported.
There were no immediate reports of damage or injuries as a result of the quake.
The Indonesian archipelago is prone to earthquakes in a belt of intense seismic activity around the rim of the Pacific Ocean.
In December 2004, a tsunami triggered by an underwater earthquake killed an estimated 230,000 people near Indian Ocean coastlines, including more than 160,000 people in Indonesia's Aceh province.
