The 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.

The Global Volcanism Program is not aware of any Holocene eruptions from Manengouba. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Manengouba page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The 3-km-wide Pleistocene Eboga caldera at the summit of Manengouba volcano lies at the extreme upper right in this Landsat image. The caldera was constructed within the indistinct 6-km-wide Elengoum caldera. Younger volcanism has constructed a SW-NE line of crater lakes and cinder cones across the caldera floor of the dominantly basaltic-to-trachytic volcano.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
