The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, impacted Portugal, the Iberian Peninsula, and Northwest Africa on the morning of Saturday, 1 November, Feast of All Saints, at around 09:40 local time.[3] In combination with subsequent fires and a tsunami, the earthquake almost completely destroyed Lisbon and adjoining areas. Seismologists estimate the Lisbon earthquake had a magnitude of 7.7[4][5] or greater[6] on the moment magnitude scale, with its epicenter in the Atlantic Ocean about 200 km (110 nmi; 120 mi) west-southwest of Cape St. Vincent, a cape in Algarve region, and about 290 km (160 nmi; 180 mi) southwest of Lisbon.
Chronologically, it was the third known large-scale earthquake to hit the city (following those of 1321 and 1531). Estimates place the death toll in Lisbon around 12,000, making it one of the largest earthquakes in history.
The earthquake accentuated political tensions in Portugal and profoundly disrupted the Portuguese Empire. The event was widely discussed and dwelt upon by European Enlightenment philosophers, and inspired major developments in theodicy. As the first earthquake studied scientifically for its effects over a large area, it led to the birth of modern seismology and earthquake engineering.
