Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

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 of Adwa. Satellitic pyroclastic cones and lava domes were considered to be only a few hundred years old (Mohr 1980, pers. comm.).
