Mousa Alli (Ethiopia-Eritrea-Djibouti)

Status Normal Eruption Unknown 1993m
Stratovolcano (Rift zone / Intermediate crust (15-25 km))

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.

Mousa Alli volcano dominates the right-hand side of this NASA Landsat image and straddles the border between Ethiopia, Eritrea, and Djibouti. This 2028-m-high trachytic-to-rhyolitic volcano is the most prominent topographic feature in this area and towers above its neighbor to the SW, Manda Inakir, visible at the lower left. Yellow-colored basaltic pyroclastic cones and associated lava flows occupy the SE and NW flanks of the rhyolitic summit massif.
