Bengkulu: Another earthquake hit Indonesia on Friday, while more than 40 aftershocks following Wednesday's strong quake triggered new panic among thousands camping out in makeshift tents.

The latest earthquake southwest of Lais Bengkulu measured 6.9 on the Richter scale, just three days after a magnitude 8.4 quake struck Sumatra.

Indonesia's meteorology agency lifted a tsunami warning issued on Friday after the latest quake struck off the southwestern coast of Sumatra island.

Wednesday's massive quake and the ensuing aftershocks killed at least 13 people, 55 injured and toppled hundreds of
buildings, according to the Indonesian health ministry.

Roads in the north of Bengkulu province, the nearest town to the epicentre of the 8.4 magnitude quake, were lined with tents where people were setting fires to keep warm.


"I just let everything and ran," said Irnawati, who had been cooking when the latest earthquake struck.

About 100 houses were damaged by a three metre wave in Serangai, north of Bengkulu city, but there were no casualties.

"Suddenly, I heard the rushing sound of water coming, it looked black. So I told everybody to run," said Johan, a farmer who uses one  name. He said most people had already fled to higher ground.

There have been nearly 40 tremors ranging in intensity from 4.9 to 7.8 since Wednesday's huge quake, repeatedly setting off tsunami warnings in Indian Ocean countries.
