JAKARTA - A MAGNITUDE 6.0 earthquake struck off Indonesia's Sumatra island on Friday, the US Geological Survey said, although there was no tsunami warning or reports of damage or casualties.

The quake was centred 141km south south-west of Bengkulu city at a depth of 35km, the agency said in a bulletin on its website.

An official at Indonesia's meteorology agency said the quake could be felt in Bengkulu and Lampung provinces in southern Sumatra, but there was no report of damage or casualties.

Indonesia suffers frequent earthquakes lying in an extremely active seismic area where several tectonic plates collide.

Last week, several strong earthquakes also struck off Bengkulu and a more powerful earthquake hit northern Sulawesi, killing at least six people.

The sprawling archipelago of more than 17,000 islands was hit by a devastating tsunami four years ago that left an estimated 170,000 people dead or missing in Aceh province. -- REUTERS
