Gas-and-steam plumes emanate from the new El Chichón crater in June 1982, about two months after a major explosive eruption formed it. The first sighting into the crater revealed three small lakes on the crater floor. These later merged into a single lake that reached a maximum depth of about 120 m. This aerial view from the east also shows gully erosion within pyroclastic flow and surge deposits on the flanks.  Photo by Wendell Duffield, 1982 (U.S. Geological Survey).
