The effects of the Great Lisbon Earthquake in Huelva and Ayamonte Page 2 Back

On the morning of November 1, 1755, a prolonged and violent earthquake struck along the Portuguese coast and was followed by a powerful tsunami. This was the first earthquake to be studied scientifically, given the large area it affected. Its effects were felt along the coast in Huelva, particularly around Ayamonte and Lepe, causing deaths and considerable damage, including virtually destroying the fishing fleet. It also took effect inland. The monarchy requested a survey of the effects of the earthquake, and other independent reports and studies were produced by people who were concerned about the situation following the disaster. Some of them, such as Antonio Jacobo del Barco, had a scientific background.
