Active Volcanoes of Chiapas (Mexico): El Chichón and Tacaná

This publication summarizes the studies carried out at two of the most active volcanoes of Chiapas (Mexico): El Chichón and Tacaná. El Chichón erupted explosively in 1982 killing more than 2000 people being the worst volcanic disaster in Mexico, and Tacaná produced two mild phreatic explosions in 1950 and 1986. Only after these explosions a surge of new studies began to unreveal their volcanic history and impact.
This book presents the state of the art advances in topics related to the geologic setting of the two volcanoes, their eruptive history and composition of erupted products, the hydrothermal systems and their manifestations. Volcanic hazards and risks and possible mitigation plans are discussed based on the experience of the catastrophic eruption of El Chichón that occurred in 1982. The book will also include previously unpublished material on the flora and the fauna of the region and archaeological and social aspects of the area that is inhabited by indigenous people.

State-of-the-art advances of the geological setting of El Chichón and Tacaná (Chiapas Region, Mexico) Hazard management based on the experiences after the 1982 eruption of El Chichón, one the biggest eruptions on Earth in the 20th century The chapter on risk assessment covers among others; human health problems related with volcanic activity, successful and unsuccessful mitigation plans, infrastructure planning, and communication strategies Includes supplementary material: sn.pub/extras
