Then the ground began to move. The magnitude 7.5 earthquake that erupted from 126 kilometers beneath the jungle was not a surface shake but an intraslab tremor, a violent flex within the subducted Nazca Plate. It traveled up through volcanic rock and rainforest soil and emerged as a sustained rolling that lasted long enough for worshippers across the border in Ecuador to feel their beds sway. A 14-meter bell tower at one of the oldest Catholic churches in the Amazonas region collapsed in a cascade of colonial stone. By sunset, rescuers were pulling bodies from a minibus that had plunged 300 meters off a damaged highway.
