BackgroundVolcán Tepetiltic is a 2020-m-high andesitic and dacitic stratovolcano, truncated by an elliptical, 5 x 2.5 km caldera that contains a lake at its NE corner. The Tepetiltic caldera has steep-sided, scalloped walls that are elongated in a NE-SW direction. The caldera originated during a major rhyodacitic eruption that produced a blanket of plinian-airfall, pyroclastic-flow, and pyroclastic-surge deposits that surrounds the volcano. Caldera collapse was closely followed by emplacement of lava domes on the eastern flank. Two andesitic domes were later emplaced on the caldera floor, and chemically unrelated flank cinder cones were erupted.
