An earthquake measuring 6.7 on the Richter scale jolted the eastern part of Indonesia early Saturday, the meteorology agency said.
No damage or casualties have been reported so far. The quake's epicentre was in the Maluku province, 194 km northwest of Saumlaki regency.
The quake was 72 km beneath the ocean, which was quite deep for the area, so there was no potential of a tsunami, the report said.
In December 2004, a 9.1 magnitude quake triggered tsunamis that struck nine countries. The waves killed some 177,000 people in Indonesia's Aceh province alone.
