Лиссабон 1755: Катастрофа, после которой Бог замолчал

On the morning of November 1, 1755 — All Saints' Day — at 9:40 a.m., something fell upon Lisbon that modern seismology still cannot name. In two minutes, of the medieval walls of the Portuguese Empire's capital only the bell towers remained. In half an hour, one in every four inhabitants was dead. In five days, the last hearths of the fire died out — and Lisbon no longer existed as a city. This is not a story about destruction. This is a story about what happened in the space that was left behind. About two men who, in December 1755, sitting in the same ruins, wrote two utterly different texts about the same event. About thirteen questions sent out across all of Portugal on January 26, 1756 — the first attempt in world history to gather seismological data through a network method. About Voltaire's poem, three texts by the young Kant, and Rousseau's letter, written within eight months of the disaster — without a single mention of God as explanation. About the last auto-da-fé in Portuguese history, which burned the preacher who explained the earthquake as God's wrath. And about a geological mystery to which science, two hundred and seventy years on, still has no answer. The magnitude of the event is still disputed — estimates range from 7.7 to 9.0. The source of the earthquake has not been definitively identified: candidates include the Marquês de Pombal Fault, the Horseshoe Fault, and the Gorringe–Glória structure. The tsunami crossed the Atlantic and reached Martinique eight hours after the first shock. But the most important legacy of the catastrophe lies not in numbers. It lies in the way we learned to ask questions about it.
