JAKARTA - A powerful 6.2-magnitude earthquake rocked the Indonesian province of Aceh early on Sunday but there were no reports of casualties or damage, an official said.

The quake, which had a depth of 30 kilometres (6.25 miles), struck in the sea south of the provincial capital Banda Aceh at 00:30 a.m. (1730 GMT), a meteorological agency official said.

Indonesia sits on the Pacific "Ring of Fire" where continental plates meet, causing frequent seismic and volcanic activity.

The earthquake-triggered Asian tsunami in December 2004 killed some 168,000 people in Aceh, which is located at the northern tip of Sumatra. Indonesia was the nation worst hit by the tsunami.
