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. An embryonic shield volcano is located on the SW side of the complex and is cut by curvilinear faults; youthful chains of spatter cones follow this same curvilinear pattern and form concentric semi-circles. The 668-m-high summit is located on the NE side of the massif and consists of a silicic stratovolcano that is the largest of the Erte Ale Range. It has produced steep-sided viscous lava flows that have traveled up to 5 km from the volcano. 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.
The Global Volcanism Program is not aware of any Holocene eruptions from Bora Ale. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Bora Ale 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.

|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 a fumarolically 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 fed very recent basaltic lava flows from a NNW-trending fissure that cuts the stratovolcano.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
