Steam pours from the new crater of El Chichón volcano in June 1982, about two months after the formation of the crater during a major explosive eruption. When the crater was first seen after the eruption on April 25, three small lakes were observed on the crater floor. These merged into a single lake that reached a maximum depth of about 120 m. This aerial view from the east also shows erosional gullying of pyroclastic-flow and -surge deposits in the foreground on the outer flanks of the crater.
