A lava flow with prominent flow levees issued from a breached cinder cone in the Mousa Alli volcanic complex. This large Holocene stratovolcano was constructed along the border between Ethiopia, Eritrea, and Djibouti 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 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 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.

Mousa Alli is located on the border of Ethiopia, Eritrea, and Djibouti, and is seen here in this December 2019 Planet Labs satellite image mosaic (N is at the top; this image is approximately 21 km across). The main edifice in the center has undergone extensive erosion and there are scoria cones and lava flows on the SE and NW flanks.
