The Global Volcanism Program is not aware of any Holocene eruptions from Afdera. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Afdera 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 massive Alayta shield volcano (center) covers an area of 2700 sq km in the western Danakil depression SW of Lake Afrera (upper right). The volcanic consists of two parts--an elongated shield volcano on the west (medium-toned) and an extensive lava field forming the dark-colored area on the eastern flank of the shield volcano. The Alayta lava field, covered by very fresh lava flows (the most recent of which was erupted in 1907), was erupted from N-S-trending fissures and laps up against the western flank of Afderà volcano (immediately SW of Lake Afrera).

|Sharp-peaked Afderà volcano rises to the SW beyond Lake Afrera (Lake Giulietti). This isolated rhyolitic stratovolcano is located at the intersection of three fault systems between the Erta Ale, Tat Ali, and Alayta ranges. Eruptions reported in 1907 and 1915 from Afderà were probably from the morphologically younger Alayta volcano. The low lakeshore tuff ring in the foreground is surrounded by lava flows erupted from vents SE of Hayli Gubbi volcano.

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.
