The Mousa Alli volcanic complex is a large Holocene stratovolcano constructed along the border between Ethiopia, Eritrea, and Djibouti. The 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. Rhyolitic lava domes and lava flows are found in the summit region, which is truncated by a caldera.

The Global Volcanism Program is not aware of any Holocene eruptions from Mousa Alli. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Mousa Alli page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The chain of pyroclastic cones and lava flows extending diagonally down from the upper-left portion of this Landsat image is the southern portion of the Mousa Alli volcanic complex. The flanks of its neighbor to the SW, Manda Inakir, are visible at the extreme lower left. Prominent faults at the right cut lava flows of the Pliocene-Pleistocene stratoid series of the Afar region.

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.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
