An earthquake of at least 6.3 magnitude has struck off eastern Indonesia's Tanimbar islands, but there was no tsunami alert, seismologists said.
The quake struck at 10:24 am local time (0124 GMT) on Sunday, 351 kilometres (217 miles) east-northeast of the East Timor capital Dili at a relatively shallow depth of 10 km, the US Geological Survey said.
The AFP news agency reported the quake's magnitude as 6.3, where as Reuters reported that it was 6.9.
The Pacific Tsunami Warning Center did not issue any alerts following the tremor in the remote region at the eastern end of the Indonesian archipelago between the islands of Timor and New Guinea.
In an initial assessment, the USGS said there was a low likelihood of damage or casualties.
Indonesia sits on the Pacific "Ring of Fire", where tectonic plates collide, causing frequent seismic and volcanic activity.
A 6.1 magnitude quake that struck Aceh province on Sumatra island in July killed at least 35 people and left thousands homeless.
