6.2-magnitude earthquake strikes off Indonesia, no casualties reported

Banda Aceh: A 6.2-magnitude quake struck off the western Indonesian island of Sumatra Sunday, prompting panicked people to run out of their homes.

However there were no reports of damage and a tsunami warning was not issued.

The US Geological Survey said the quake hit at a depth of nine kilometres (six miles), just over 300 kilometres west of the coastal city Banda Aceh.

It occurred at around 7:00 am (0100 GMT), USGS said.

"The quake was felt strongly for a few seconds by residents on the west coast," said national disaster agency spokesman Sutopo Purwo Nugroho.

"Some people ran out of their homes."

But he added there had been no reports of damage.

Mochammad Riyadi, from the Indonesian meteorology, climatology and geophysics agency, also said there were no reports of casualties or damages.

"The magnitude may be big but the epicentre is at sea and relatively far away from the nearest city, Banda Aceh," he told AFP.

Banda Aceh was devastated by a huge tsunami in 2004, which killed some 170,000 people in the surrounding region, as well as tens of thousands more in countries around the Indian Ocean. 

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