A geological field party on horseback rides through the area devastated by pyroclastic surges during the 1982 eruption of El Chichón. Pyroclastic flows and surges swept a roughly circular area of about 150 km² radially from the summit to distances up to 8.5 km from the vent. Nine villages were within the devastated zone and thousands of people were killed.
