Mexican scientists finger volcanoes as a cause of Mayas' collapse
Government officials are concerned that a sudden, explosive eruption of Popocatépetl or one of the other volcanoes within the metropolitan area could cause several million casualties. It would be impossible to evacuate a substantial percentage of the mega-city’s population on short notice. There is also the ever present danger that a new volcano will suddenly push through the soil in a densely populated area. It has happened before in Mexico. There is almost nothing an architect can do to prevent catastrophe when a building is subjected to direct contact with molten lava. The structure either burns or melts.
Around 150 AD the Xitle volcano in the suburbs of present day Mexico City erupted, causing the abandonment of two cities, Cuicuilco and Copilco. They were later covered by lava. Around 930 AD the Xocoteptl volcano in the northwest suburbs of Mexico City exploded with a force equal to or greater than Krakatoa (Indonesia) in 1883. Had that explosion occurred today, perhaps five million people would have been killed.
