Mousa Alli Volcano — Ethiopia-Eritrea-Djibouti

The Mousa Alli volcanic complex is a large Holocene stratovolcano constructed along the border between Ethiopia, Eritrea, and Djibouti. The trachytic-to-rhyolitic volcano is the most prominent topographic feature in this area. Rhyolitic lava domes and lava flows are found in the summit region, which is truncated by a caldera.
