Overview
As the southernmost axial range of western Afar, the Manda Hararo complex is located in the Kalo plain, SSE of Dabbahu volcano. The massive 105-km-long and 20-30 km wide complex represents an uplifted segment of a mid-ocean ridge spreading center. A small basaltic shield volcano is located at the N end of the complex, S of which is an area of abundant fissure-fed lava flows.
Two basaltic shield volcanoes, the larger of which is Unda Hararo, occupy the center of the complex. The dominant Gumatmali-Gablaytu fissure system lies to the S. Voluminous fluid lava flows issued from these NNW-trending fissures, and solidified lava lakes occupy two large craters.
The small Gablaytu shield volcano forms the SE-most end of the complex. Lava flows from Gablaytu and from Manda overlie 8,000-year-old sediments. Hot springs and fumaroles occur around Daorre lake.
The first historical eruptions produced fissure-fed lava flows in 2007 and 2009.

About the Photo
Steam rises from new fissures that fed lava flows at the Manda Hararo complex, as seen on 20 August 2007. The Manda Hararo complex is the southernmost axial range of western Afar. The massive complex is 105 x 20-30 km and represents an uplifted segment of a mid-ocean ridge spreading center. Voluminous lava flows erupted from NNW-trending fissures.
