At 3:58 AM local time on December 18, 1979, the earth beneath Bali's eastern coast shifted violently, registering a surface-wave magnitude of 6.3. Within seconds, homes built from volcanic stone and timber began to collapse across an entire regency. Up to eighty percent of buildings in Karangasem were damaged or destroyed, and between 15,000 and 500,000 people found themselves suddenly without shelter. The road linking Karangasem to the provincial capital of Denpasar, sixty kilometers to the southwest, was severed. In the predawn darkness, thousands of residents fled their crumbling homes and spent the rest of the night huddled on beaches and in open fields, too terrified to return indoors.
