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 sq km 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.
