The steaming crater of El Chichón volcano is seen here in January 1983, less than a year after a major explosive eruption formed a new 1-km-wide crater that later was partially filled by a steaming, acidic lake. The isolated El Chichón volcano is a small, but powerful andesitic tuff cone and lava dome complex. Prior to 1982, this relatively unknown volcano was heavily forested and of no greater height than adjacent non-volcanic peaks. More than a half dozen large explosive eruptions have occurred since the mid-Holocene.
