In the early 1980s, Ecuadorian emigration also saw a spike as oil prices fell due in part by the 1980s oil glut. The reduced demand for oil following the 1970s energy crisis caused for a surplus of crude oil. This resulted in Ecuador suffering an economic recession, as oil accounted for the country’s largest and main source of revenue. Another cause of Ecuadorian emigration was the El Niño event during 1982–1983. Other resources existing within Ecuador were severely damaged due to the extreme climate conditions caused by El Niño, which included floods, landslides, and torrential rains. Their fishing industry, another source of revenue, especially suffered due to a failed anchovy harvest and sardines unexpectedly moving south toward Chilean waters.
