Mount Alayta is a shield volcano in the Afar Region of Ethiopia. Part of the Afar Triangle (Afar Depression), a highly active volcanic region which includes the adjacent Mount Afdera, this volcano covers an area of 2700 square kilometers southwest of Lake Afrera. A chain of younger craters are aligned along a north-northwest axis in the basaltic-to-trachytic shield along the east side of the shield volcano, which extends to the western flank of Mount Afdera. The Alayta Lavafeld covered by fresh lava streams was formed from a series of north-south fissures. In two areas on the southern side of the volcanic complex, fumaroles can be observed.
Two historical eruptions that were formerly attributed to Mount Afdera are believed to have originated from Alayta. One of those eruptions, between June and August 1907, produced a large lava flow from a vent on its southeastern flank. Its most recent eruption was in 1915.
