The Global Volcanism Program is not aware of any Holocene eruptions from Ale Bagu. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ale Bagu page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Photo Gallery


Ale Bagu, also known as Ummuna, is an elongated, 1031-m-high stratovolcano (left center) located SW of Erta Ale, the volcano at the top-center showing a small orange-colored lava lake. In contrast to other volcanoes of the Erta Ale Range, Ale Bagu is mantled by basaltic pyroclastic rocks. The main crater is a steep-walled, 750 x 450 m depression; trachytic lava flows occupy the crater floor, and silicic lavas from the axial regional fissure extend to the NW and SE. Lake Giulietti (also known as Lake Afrera) is at the lower right.

The prominent peak near the center of this NASA Landsat image (with north to the top) is Ale Bagu, also known as Ummuna. This elongated, 1031-m-high stratovolcano is the highest of the Erta Ale Range volcanoes, and unlike other volcanoes in the massif, is mantled by basaltic pyroclastic rocks. The main crater is a steep-walled, 750 x 450 m depression prominent in this image. The light-colored Roram Plain lies at the lower left, and lava flows from Hayli Gubbi volcano are visible at the right.
