1755 Lisbon earthquake
earthquake in 1755 / From Wikipedia, the free encyclopedia
The 1755 Lisbon earthquake was a major earthquake that hit Portugal and the rest of the Iberian Peninsula on 1 November 1755.[1] The earthquake caused serious damage to Lisbon. It killed an estimated 60,000 people in Lisbon alone.[2] Violent shaking destroyed about 12,000 homes. Because November 1, when the quake struck, was All Saints' Day, many people were attending mass at the time of the quake. Churches collapsed and many people died.
