The Kone volcanic complex, also known as Gariboldi, is composed of a series of silicic calderas and young basaltic cinder cones and lava flows about 30 km SW of Fentale volcano. As many as eight silicic calderas are accompanied by ignimbrite outflow sheets. Gariboldi, the youngest caldera, is an elliptical 5 x 7.5 km wide caldera trending E-W and oriented perpendicular to the Main Ethiopian Rift. The rim of the caldera rises about 100 m above the caldera floor; the eastern rim overlaps with a smaller elliptical caldera. Roughly N-S-trending regional fissures cut across the caldera and its flanks. The youngest basalts were erupted during the first half of the 19th century from vents along a hinge line between the smaller eastern caldera and the larger western one.

The Kone volcanic complex, also known as Gariboldi, is composed of a series of silicic calderas and young basaltic cinder cones and lava flows. North lies to the lower left in this Space Shuttle image. The dark-colored basaltic lava flows on the caldera floor were erupted during the first half of the 19th century along a hinge line between a smaller caldera on the east and a larger, 5-km-wide caldera on the west. The larger young lava flow at the right was erupted from a vent on the SE flank.

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.
