Case Study 9. Active Volcanoes in Mexico as Tourist Destinations
El Chichón is located in north-western Chiapas State. Its only recorded eruptive activity was between 29 March and 4 April 1982, when it produced a 1km wide caldera that then filled with an acidic crater lake (Robock, 2002). The eruption killed 2000 people who lived near the volcano. El Chichón is part of a geologic zone known as the Chiapanecan Volcanic Arc, thought to be the result of the subduction of the Tehuantepec Ridge, an undersea ridge which lies on the Cocos Plate off the Pacific coast of Mexico (Manea and Manea, 2005).
