The 1687 Peru earthquake occurred at 11:30 UTC on 20 October 1687. It had an estimated magnitude of 8.4–8.7 and caused severe damage to Lima, Callao and Ica. It triggered a tsunami and overall, about 5,000 people died.
Tectonic setting
[edit]The earthquake occurred along the boundary between the Nazca plate and the South American plate. The earthquake is likely to be a result of thrust faulting, caused by the subduction of the Nazca plate beneath the South American plate.
The coastal parts of Peru and Chile have a history of great megathrust earthquakes originating from this plate boundary, such as the 1960 Valdivia earthquake.
Damage
[edit]The port of Pisco was completely destroyed by the tsunami, with at least three ships being swept over the remains of the town.[2]
Characteristics
[edit]The earthquake was probably followed by another large event further to the south.[2] A magnitude of 8.7 has been estimated from tsunami runup heights and by comparison with the earthquake of 1974.[3]
The tsunami was reported in Japan where it produced runups of tens of metres.[2]
Economic impact
[edit]Chile has a history of exporting cereals to Peru dating back to 1687 when Peru was struck by both an earthquake and a stem rust epidemic.[4] Chilean soil and climatic conditions were better for cereal production than those of Peru and Chilean wheat was cheaper and of better quality than Peruvian wheat.[4][5] According to historians, Villalobos et al. 1974 the 1687 events were only the detonant factor for exports to start.[4]
In the 16th and 17th century, the principal wine growing area of the Americas was in the central and southern coast of Peru.[6] In Peru, the largest wine-making centre was in the area of Ica and Pisco.[6] The earthquake destroyed wine cellars and mud containers used for wine storage.[7] This event marked the end of the Peruvian wine-boom.[8]
