The north crater of Ol Doinyo Lengai, seen here from its NE rim in July 1988, has been the source of all historical eruptions from the volcano. The second crater is located on the other side of the summit peak. A decade-long eruption beginning in 1983 produced a series of lava flows on the floor of the crater. By December 1988 lava had overflowed into a shallow depression below and to the right of the summit.
