Borale Ale

Bora Ale

Stratovolcano · Ethiopia · 668m

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.

Geological summary

Bora Ale is a complex volcano located near the center of the Erta Ale Range. The earliest activity formed submarine lava flows partially covered by Quaternary reef deposits. A 4-km-wide shield volcano SW of the main cone is cut by curvilinear faults; youthful chains of spatter cones follow this same pattern and form concentric semi-circles. The summit is located on the NE side of the massif and consists of a silicic stratovolcano that is the largest of the Erta Ale Range. It has produced steep-sided viscous lava flows that have traveled up to 5 km. Strong fumarolic activity occurs within a 300-m-wide summit crater. Regional faulting has fed very recent basaltic lava flows from a NNW-trending fissure that cuts the stratovolcano.
