El Nino 1982-83

Authors(s) and Affiliation(s)



The eastern tropical Pacific and areas along its fringe in South America experienced the most intense El Nino occurrence of the twentieth century beween June 1982 and July 1983. At least twenty-five spells of bad weather caused extensive damage to agriculture, structures, and transportation in southern Ecuador, Peru, the Galapagos Islands, and eastern Polynesia. The basins of the Tumbes, Chira, Piura, Lambayeque, Zana, Reque, Jequetepeque, Chicama, Moche, and Viru rivers in Peru were the most affected areas. In the ocean reduced fish stocks caused starvation among seabirds and mammals. The altiplano highlands suffered severe drought. There is a coincidence between past El Nino occurrences and tropical volcanic activity. The eruption of El Chinchon in April 1982 appears to be closely related to El Nino 1982-83.
