| 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. | |||
