Similarly at Muko Muko town of Bengkulu province, the second closest area to the quake center, there were no report of damages or casualty, a military officer at the town Military Command, Rudi Hartono, said.

"The shakes of the quake was long but not strong. The people rushed out from their homes. There were no building damages or casualty," Hartono told Xinhua by phone from the province.

The National Disaster Management Agency official Adam Malik also confirmed that the quake did not cause damages in the whole province.

Twenty-three people were killed and thousands of buildings were destructed in September 2007 after a 7.9-magnitude quake rocked Bengkulu province in Sumatra Island of western Indonesia.

In 2004, over 170,000 people died in Aceh province in northern tip of Sumatra Island after a tsunami triggered by a powerful quake devastated coastal areas of the province and others countries in southeast Asia.

Indonesia is laid at a vulnerable zone, so called "the Pacific Ring of Fire" where two continental plates, stretching from the Western Hemisphere through Japan and Southeast Asia, meet, which causes frequent volcanic movements.
