Manda-Inakir volcano consists of a series of NW-trending fissure vents and pyroclastic cones along the Ethiopia-Djibouti border. The elongated complex represents an uplifted mid-ocean ridge spreading center now exposed above sea level. An elongated dome of basement rocks is cut by two axial rifts, the northern of which was active during historical time. Basaltic cinder cones along marginal faults of the rift have produced lava flows that traveled down the flanks of the structural dome, producing a shield-like morphology. An eruption in 1928 or 1929 at the SE end of the Manda-Inakir rift near the town of Korili (in Djibouti) produced the Kammourta cinder cone and a lava flow.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The dark-colored lava flows extending diagonally across the center of this Landsat image were erupted from pyroclastic cones of Manda-Inakir volcano. These NNW-trending fissure vents and cones are located along the Ethiopia-Djibouti border and represent an uplifted mid-ocean ridge spreading center now exposed above sea level. An eruption in 1928 or 1929 at the SE end of the Manda-Inakir rift near the town of Korili (in Djibouti) produced the Kammourta cinder cone and a lava flow.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
