Djibouti lies in northeast Africa on the Gulf of Aden at the southern entrance to the Red Sea. It is situated near a tectonic triple junction where three tectonic plates meet - African, Arabian, and Somali.
There are two rifts zones in Djibuti: the active Asal rift (birthplace of the Ardoukba basaltic volcano in 1978) and the poorly known Manda- Inakir rift which produced 1928-29 eruption of Manda-Inakir volcano.
