Manda Hararo

Manda Hararo is a group of basaltic shield volcanoes in east Africa that last erupted in 2009. The group is very large, spreading over 105 square kilometres (41 sq mi). At its northern end is a small cluster. South of this volcano is the Gumatmali-Gablaytu fissure system, an area dominated by fissure-fed lava flows. At the centre of the complex rise two volcanoes. Manda Hararo's large size is because it is a raised block from the end of a mid-ocean ridge spreading center. It is known for its rare basalts.
