A strong 6.1-magnitude earthquake struck off Indonesia's Sumatra island on Saturday, the US Geological Survey said, but no tsunami warning was issued.

The quake struck at 5:14 am (2314 GMT Friday) at a depth of about 34 kilometres (21 miles), 427 kilometres southwest of Banda Aceh on the northern tip of Sumatra. There were no immediate reports of damage.

Aceh province was shaken earlier this month by two huge earthquakes, triggering an Indian Ocean-wide tsunami alert.

At a magnitude of 8.6, the first of the two quakes was the strongest to hit since the 2004 Indian Ocean tsunami that killed 170,000 in Aceh. No major damage was reported.
