A magnitude 7.7 earthquake Monday triggered towering waves that smashed into a 110-mile stretch of Java's southern coast, destroying scores of houses, restaurants and hotels. Cars, motorbikes and boats were left mangled amid fishing nets, furniture and other debris.

Emergency teams keep pulling out corpses from the ruins.

Indonesia's national disaster coordinating board said Friday that 547 people had been killed and 323 others were missing.
