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 lava flow at the left was erupted on the caldera floor of Fentale volcano in 1820. This view looks from the east. The walls of the 3 x 4 km summit caldera of Fentale are up to 500-m high. During the 1820 eruption, basaltic lava flows were also extruded onto the Main Ethiopian Rift from a 4-km-long fissure on the south flank.

|A vertical aerial photo of the Quaternary Fentale volcanic complex, lying along the main Ethiopian rift zone, shows its prominent summit caldera and lava flows forming its flanks. The 3 x 4 km caldera with steep-sided walls up to 500 m high is elongated perpendicular to the direction of the regional fissures of the Ethiopian Rift. Note the recent rhyolitic obsidian lava flow to the NE (upper right) marked with curved flow ridges. The dark lava flow on the caldera floor was erupted in 1820.

|The caldera of Fentale volcano, also known as Fantale, is seen in a fish-eye lens view from the NE caldera rim. Welded pantelleritic ash flows accompanied formation of a 2.5 x 4.5 km summit caldera, which has steep-sided walls up to 500 m high. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift, and post-caldera vents occur along the same orientation. Trachytic and obsidian lava flows occur on the caldera floor, and lava flows were erupted on the floor of the caldera and on its flanks in 1820.

|Fentale, also known as Fantale, is a large stratovolcano seen here in profile from the arid floor of the Ethiopian Rift. Fentale lies at the northern end of the Main Ethiopian Rift and consists primarily of rhyolitic obsidian lava flows with minor tuffs. Welded pantelleritic ash flows accompanied formation of a 2.5 x 4.5 km summit caldera, which has steep-sided walls up to 500 m high. The WNW-ESE-trending elliptical caldera has an orientation perpendicular to the Ethiopian Rift, and post-caldera vents occur along the same orientation.

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.
