The new 1-km-wide El Chichón crater is seen here in January 1983, less than a year after the major explosive eruption . By this time it was partially filled by a hot, acidic lake. The isolated, low-profile, volcano is a small lava dome complex that was heavily vegetated prior to 1982. More than a half-dozen large explosive eruptions have occurred since the mid-Holocene.
