The Manengouba volcanic complex is located across the Tombel Graben from Mount Cameroon. Growth of the initial Manengouba shield volcano during the early Pleistocene was followed by growth of the Eboga stratovolcano. The subsequent Elengoum extrusive complex consists of trachytic pyroclastic flows and trachyandesitic to trachytic lava domes, and magma withdrawal associated with these eruptions was linked to formation of the 4-km-wide Eboga caldera. Renewed eruptions within the caldera and on its flanks produced about one hundred pyroclastic cones and three maars during the latest stage of activity at Manengouba that were dated between about 0.45 and 0.11 Ma.
