This ebook offers the state-of-the-art advances in issues with regards to the geologic surroundings of the 2 volcanoes, their eruptive historical past and composition of erupted items, the hydrothermal structures and their manifestations. Volcanic dangers and dangers and attainable mitigation plans are mentioned in accordance with the event of the catastrophic eruption of El Chichón that happened in 1982. The booklet also will comprise formerly unpublished fabric at the flowers and the fauna of the zone and archaeological and social elements of the world that's inhabited by way of indigenous humans.
