In late April 1982, following a series of powerful explosive eruptions from March 28 to April 4 that created a new 1-km-wide crater at El Chichón volcano, a lake began forming on the crater floor. By November the lake was up to 600 m wide and about 120 m deep. Vigorous steam plumes rise from fumaroles below the west crater wall in this March 28, 1983 photo. In January 1983 the lake was hot (52-58 degrees Centigrade) and acidic (pH of 0.5).
