El Chichón is an active volcano in northwestern Chiapas, Mexico. Its only recorded eruption was in 1982, when it produced a 1km-wide caldera that then filled with an acidic lake. The eruption killed around 2 000 people which lived near the volcano. In 2000, the lake's water temperature increased. It had high-sulphur anhydrite-bearing magma explosive eruptions with pyroclastic flows and surges that were devastating.
