Dabbayra (center), the westernmost volcano of the Afar depression, lies near the edge of the Ethiopian escarpment. In contrast to structural trends in other parts of Afar, Dabbayra (also known as Bar-Ali) consists of a basaltic shield volcano elongated in an ENE-WSW direction. The only silicic volcanic rocks are a NNW-trending line of lava domes and lava flows near the crest of the volcano

Resumen geológico

Dabbayra, the westernmost volcano of the Afar depression, was constructed along an offshoot of the Ethiopian escarpment, SW of the Teru plain. In contrast to structural trends in other parts of Afar, Dabbayra (also known as Bar-Ali) consists of a basaltic shield volcano elongated ENE-WSW. The only silicic volcanic rocks are a NNW-trending line of lava domes and lava flows near the crest of the volcano.
