Powerful Indonesian Quake Kills 3

A powerful earthquake struck western Indonesia on Wednesday, killing at least three people, injuring more than two dozen, and damaging many buildings, officials said.

The quake prompted officials to put a tsunami warning in place, but that was later dropped when no large waves were detected.

The U.S. Geological Survey said the quake had a preliminary magnitude of 7.6 and struck under the island of Simeulue off the western coast of Sumatra - the region worst hit in the 2004 Indian Ocean tsunami.

Rustam Pakaya, the head of the Indonesian Health Ministry's disaster center, said "many" buildings on Simeulue were damaged and three people were killed. He said at least 25 others were seriously injured.

The Pacific Tsunami Warning Center issued an alert saying coastlines close to the epicenter were at risk of a possible tsunami. It canceled the warning two hours later after no large waves were generated.

The quake was felt across much of western and northern Sumatra, where many people fled swaying homes and buildings. In coastal areas, residents ran to high ground in fear of a tsunami.

"Everything shook very strongly for more than a minute and I ran along with the others. I heard people screaming in panic," said Ahmad Yushadi, a resident of Aceh province on the northern tip of the island.

Quakes measuring 7 and above can cause major damage in built-up areas.

Simeulue is home to around 75,000 people, but most people live in simple village homes that do not typically cause major injuries or death to inhabitants if they collapse.

Many of the island's two-story brick buildings collapsed during quakes in 2004 and 2005 and remain unused.

Indonesia, the world's largest archipelago with a population of 235 million people, is prone to seismic upheaval because of its location on the "Ring of Fire," an arc of volcanos and fault lines encircling the Pacific Basin.

The Indian Ocean fault that ruptured Wednesday off the coast of Sumatra is particularly deadly.

A magnitude-9 quake there in 2004 triggered a tsunami that killed more than 230,000 people in a dozen countries, most of them on Sumatra. Three months later, an 8.7 quake further down the fault killed 1,000 on the islands of Nias and Simeulue.
