The Lima–Callao earthquake
A tsunami wiped out Peru's main port

On 28 October 1746 an earthquake of estimated magnitude 8.6–8.8 destroyed much of Lima, capital of the Viceroyalty of Peru. Soon afterwards a tsunami struck the port of Callao: of its roughly 5,000 inhabitants, by various accounts only about 200 survived. Lima was rebuilt with lower houses and lighter upper storeys, and the disaster ranks among the most severe in South American history.
