Overview
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.

About the Photo
Mousa Alli volcano dominates the right-hand side of this NASA Landsat image and is located on the border between Ethiopia, Eritrea, and Djibouti. This 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.
