Geological summary

Adwa (also known as Aabida, Amoissa, or Dabita), is a broad stratovolcano in the southern Afar area immediately east of the younger vegetated Ayelu volcano. It has a roughly 3 x 4 km caldera that originated following eruption of voluminous ignimbrites, with a trachytic dome extruded in the eastern part of the caldera. Scoria cones are located on the floor of the caldera and on its NW and SW flanks. Extensive young basaltic lava flows cover the flanks 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.). Dark lava flows originating from cones about 4 km from the caldera rim on the SW flank cover more than 50 km2.

Separate activity dataset

Weekly volcanic activity reports

Preliminary and selective

Smithsonian/USGS weekly reports are selective and preliminary. They are not a comprehensive list of all eruptions or volcanic activity.

No weekly report appears on this page. Absence from the weekly report does not establish an absence of volcanic activity.

Historical catalogue records

Eruption history

Dates can be approximate, incomplete, or BCE. These are historical catalogue observations, not a statement about present activity.
