Manda-Inakir

Geography & Climate

Manda-Inakir is located in Ethiopia-Djibouti, within the Afar Rift Volcanic Province of the broader Eastern Africa Volcanic Regions. Situated at 12.38° N, 42.20° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. With a summit elevation of 600 meters above sea level, Manda-Inakir is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.

Geological Context

Manda-Inakir is situated along a rift zone, where tectonic plates are pulling apart. As the crust thins and fractures, magma rises to fill the gap, creating volcanic activity. Rift volcanism typically produces more fluid lava flows rather than explosive blasts, which means communities near Manda-Inakir in Ethiopia-Djibouti generally face slower-moving hazards like lava flows and ground fissures rather than sudden pyroclastic events. However, rift volcanoes can still generate significant ash emissions and gas releases that affect local air quality. The dominant rock type is basalt / picro-basalt, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.

Eruption History Summary

Manda-Inakir has 1 recorded eruption in the geological database, spanning from 1928 CE to 1928 CE. The most powerful recorded event was an explosive event producing ash plumes up to several kilometers in 1928 CE, reaching VEI 2 on the Volcanic Explosivity Index. The most recent eruption in 1928 CE places this volcano within the modern era of volcanological observation.

GVP Reference Summary

Manda-Inakir consists of a series of NW-trending fissure vents and pyroclastic cones along the Ethiopia-Djibouti border. The elongated complex represents an uplifted mid-ocean ridge spreading center now exposed above sea level. An elongated dome of basement rocks is cut by two axial rifts, the northern of which was active during historical time. Basaltic cinder cones along the rift's marginal faults have produced lava flows on the flanks of the structural dome, yielding a shield-like morphology. An eruption in 1928 or 1929 at the SE end near the town of Korili (in Djibouti) produced the Kammourta cinder cone and a lava flow.
