Disaster fell upon Portugal in the morning of 1 November 1755, when Lisbon was struck by a violent earthquake with an estimated moment magnitude of 8.5–9. The city was razed to the ground by the earthquake and the subsequent tsunami and ensuing fires. Carvalho e Melo survived by a stroke of luck and then immediately embarked on rebuilding the city, with his famous quote: "What now? We bury the dead and take care of the living."
