Powerful earthquakes and aftershocks continue to shake Indonesia's western Sumatra island, forcing jittery residents to camp outside their homes two days after the first powerful quake struck.
The earthquakes have triggered tsunami warnings that have been periodically issued and then lifted. Officials say a magnitude of 6.9 quake hit Friday 153 kilometers northwest of Bengkulu, triggering a brief tsunami warning.
Witnesses say at least one three-meter high tsunami wave hit Sumatra's southern coast, damaging about 100 homes.
Indonesian officials say at least 14 people have been killed and hundreds of houses damaged in the wake of Wednesday's powerful 8.4 temblor.
Overall, officials say the damage has been minimal, but some remote areas have not yet been reached.
A U.N. assessment team visited Bengkulu, an area near the epicenter of the quake on Thursday, and said there is no need for a major international relief effort.
The Indonesian archipelago is prone to seismic activity because of its location on an arc of volcanos and fault lines circling the Pacific Basin.
In December 2004, a tsunami triggered by an underwater earthquake killed an estimated 230,000 people near Indian Ocean coastlines, including more than 160,000 people in Indonesia's Aceh province.
