MEUREUDU, Indonesia — A strong earthquake rocked Indonesia’s Aceh province early on Wednesday, killing nearly 100 people and sparking a frantic rescue effort in the rubble of dozens of collapsed and damaged buildings.

Maj. Gen. Tatang Sulaiman, chief of the army in Aceh province, said at least 97 died while four people were pulled from the rubble alive. Another four or five are known to be buried, but he didn’t say if they are dead or alive.

“Hopefully we would be able to finish the evacuation from the rubble before sunset,” said Sulaiman.

The rescue effort involving thousands of villagers, soldiers and police is concentrated on Meureudu, a severely affected town in Pidie Jaya district. Excavators were trying to remove debris from shop houses and other buildings where people were believed buried. TV footage showed rescuers in orange uniforms shining flashlight into the interiors of broken buildings as they searched for signs of life.

The National Disaster Mitigation Agency said 273 people were injured, about a quarter of them seriously. Some 245 buildings were seriously damaged or destroyed, mostly in Pidie Jaya, including 14 mosques and the remainder largely dwellings and shop houses. Roads also cracked and power poles toppled over.
