Adwa, also known as Aabida, Amoissa, or Dabita, is a stratovolcano in the southern Afar area immediately east of Ayelu volcano. Adwa is younger than the vegetated Ayelu and is a stratovolcano with a 4 x 5 km caldera that originated following eruption of voluminous ignimbrites. A small 2.5-km-wide caldera cuts a trachytic dome extruded in the older caldera. Scoria cones are located on the floor of a circular summit caldera and on its NW and SW flanks. Extensive young basaltic lava flows cover the flanks of Adwa and overlap a sedimentary plain to the SE. Many fumaroles occur within the caldera. Satellitic pyroclastic cones and lava domes were considered to be only a few hundred years old (Mohr 1980, pers. comm.).

A 4 x 5 km wide caldera cuts the summit of Adwa volcano above the center of this NASA Landsat image with north to the top. This prominent volcano (also known as Aabida, Amoissa, or Dabita) is a stratovolcano in the southern Afar area immediately east of Ayelu volcano, which lies above and to the left of the westernmost flank lava flow. These prominent young basaltic lava flows were erupted from vents on the west, east, and south flanks of Adwa volcano and overlap a sedimentary plain to the SE.

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.
