Ale Bagu Volcano — Ethiopia

Ale Bagu, also known as Ummuna, is an elongated stratovolcano located SW of Erta Ale volcano. In contrast to other volcanoes of the Erta Ale Range, it is located SW of the axis of the range, and is mantled by basaltic pyroclastic rocks. Summit craters are elongated along a NNW-SSE trend. The main crater is a steep-walled, 750 x 450 m depression occupied by a steep-sided lava cone that has fed trachytic lava flows over the crater floor. Silicic lavas from the axial regional fissure extend to the NW and SE.
