Mount Kilimanjaro - Geology

Geology

Kilimanjaro is composed of three distinct volcanic cones: Kibo 5,895 m (19,341 ft); Mawenzi 5,149 m (16,893 ft); and Shira 3,962 m (13,000 ft). Uhuru Peak is the highest summit on Kibo's crater rim.

Kilimanjaro is a large stratovolcano. Two of its three peaks, Mawenzi and Shira, are extinct while Kibo (the highest peak) is dormant and could erupt again. The last major eruption has been dated to between 150,000 and 200,000 years ago.

Although it is dormant, Kibo has fumaroles that emit gas in the crater. Several collapses and landslides have occurred on Kibo in the past, one creating the area known as the Western Breach.
