Background

Manda Hararo complex is located on the southernmost axial range of the western Afar triangle, inside the Kalo plain, SSE of Dabbahu volcano. The first historic eruption witnessed at this volcano took place in August 2007, when a series of cracks opened in the ground, some of which erupted basaltic lava flows. The activity was accompanied by an intense seismic activity and many signs of ground deformation typical of rift spreading zones. The massive complex is 105 km long and 20-30 km wide, and represents an uplifted segment of a mid-ocean ridge spreading center. A small basaltic shield volcano is located at the northern end of the complex, south of which is an area of abundant fissure-fed lava flows. Two basaltic shield volcanoes, the largest of which is Unda Hararo, occupy the center of the complex. The dominant part of the complex lies to the south, where the Gumatmali-Gablaytu fissure system is located. 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 Manda Hararo complex. Lava flows from Gablaytu and from Manda overlie 8000-year-old sediments. Hot springs and fumaroles occur around Daorre lake.

Manda Hararo volcano (Ethiopia) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 July-14 July 2009 (New Activity / Unrest)

A large sulfur dioxide plume and several thermal anomalies from Manda Hararo that were detected in satellite imagery during 28-30 June prompted a science team to visit the area on 4 July. After conducting ground-based and aerial observations for approximately 2 hours, they reported that the eruption occurred near the August 2007 eruption site, and was possibly bigger than that event. No active lava effusion was seen, but steaming was observed from the 4-5 km-long fissure that, because of high temperatures, had to be observed from a distance. ... Read all

Manda Hararo volcano (Ethiopia) - Smithsonian / USGS Weekly Volcanic Activity Report for 1 July-7 July 2009 (New Activity / Unrest)

A large sulfur dioxide plume and several thermal anomalies from Manda Hararo were detected in satellite imagery during 28-30 June. Thermal anomalies detected in satellite imagery indicated a surface lava flow in the Karbahi region. Karbahi is a graben area with numerous active faults, fissures, and basalt flows, NW of the center of the broad Manda Hararo volcanic complex. ... Read all
