1755年葡萄牙里斯本大地震

The Lisbon earthquake of 1 November 1755 struck with an estimated magnitude of 8.5, killing about 50,000 people and reaching Mercalli intensity XI. Occurring on All Saints' Day, the shock, the fires that followed, and a great tsunami together destroyed much of the Portuguese capital. The rupture is attributed to faults near the Eurasian–African plate boundary in the Atlantic, southwest of Iberia. The disaster reverberated through European thought, prompting influential debate among Enlightenment philosophers and helping to inspire the systematic study of earthquakes that is regarded as a foundation of modern seismology.
