BackgroundThe well-preserved Manengouba stratovolcano rises to 2411 m across the Tombel Graben from Mount Cameroon and has two concentric summit calderas, Elengoum and Eboga. The older 6-km-wide Elengoum caldera is poorly defined and probably formed between about 800,000 and 600,000 years ago. Large lava flows traveled down the NE flanks from a breach on the eastern caldera rim. The younger 3-km-wide Eboga caldera is thought to have formed about 250,000 years ago. Younger volcanism of unknown age has constructed a SW-NE line of crater lakes and cinder cones across the caldera floor of the dominantly basaltic-to-trachytic volcano.
