Manda-Inakir Volcano | John Seach


Afar Depression, Djibouti/Ethiopia

12.38 N, 42.20 E
summit elevation 600 m
fissure vents

Manda-Inakir volcano is located in NE Ethiopia and parts of the rift zone cross the border into Djibouti.

The Manda-Inakir Range contains two rift zones.
1) The older Inakir rift, north of Dorra contains volcanic rocks overlying a NW-SE-enlongated dome (12 x 25 km). The dome is cut by a 2-3 km wide rift zone.

2) The volcanically active Manda rift has a general NW-SE trend, parallel to the Inakir structure. Most of the Manda rift lies in Ethiopia; only its southern end projects into Djibouti. In Djibouti, the rift zone is 2 km wide and is densely fractured.

Kammourta volcano is a basaltic cinder cone 400 m high and 400 m width at its base, from which two broad lobes of thick a'a lava flowed toward the Andabba Plain

1928-29 Eruption
Local residents report an eruption of Manda-Inakir volcano was accompanied by strong earthquakes, which made it difficult to stand. Residents of Korili village (10 km from Kammourta volcano) saw dust rising high into the sky and heard explosions like cannon shots. The earthquakes lasted for one month, and fractured opened up on the southwest side of the Andabba Plain.
