| 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.). | |||
