Global Volcanism Program | Image GVP-09914

The summit of Borale Ale (upper left) consists of a silicic stratovolcano that is the largest of the Erte Ale Range. Spatter cones aligned along regional fissures can be seen in the foreground and an altered lava dome forms the light-colored cone above the fissures. Strong fumarolic activity occurs within a 300-m-wide crater on the 668-m-high summit of the volcano. Regional faulting has resulted in recent basaltic lava flows from a NNW-trending fissure that cuts the stratovolcano.
