The Mousa Ali Volcano is a 2,021 metres (6,631 ft) stratovolcano located on the tri-point borders of Ethiopia, Eritrea and Djibouti. The volcano is the highest point in Djibouti. The volcano's summit is truncated by a caldera, which contains rhyolitic lava domes and lava flows.[2] The last known eruption occurred before the Holocene era.

Mousa Ali is situated at the tri-point of the Tadjourah Region of Djibouti; the Southern Red Sea Region of Eritrea; and the Afar Region of Ethiopia.


The position of Ali Mousa as tripoint between Ethiopia, Eritrea and Djibouti is not the result of an agreement between the three countries. In December 1948 the British administering Eritrea refused to attend a meeting on site with the other two parties to determine the exact item. From 1952, he is no longer that of an internal border to Ethiopia. In 1954, Ethiopian delegates, however, refuse to demarcate the border of Eritrea.

This boundary becomes international in 1993 During the arbitration process, which sets the border between Eritrea and Ethiopia, Ethiopia boasts a tripoint further east, to Dadda'to. Finally, the Permanent Court of Arbitration sets the tripoint to Djibouti.
