The Ambre-Bobaomby volcanic field at the northern tip of Madagascar consists of Miocene volcanics capped by very recent cones. The earliest volcanism produced a large basaltic massif and minor pyroclastic flows. Tertiary to Quaternary volcanic rocks span a wide geochemical spectrum, including basaltic, andesitic, rhyolitic, trachytic, phonolitic, and foiditic compositions. The young volcanoes have very well-preserved morphologies and were mapped as Recent (Besairie, 1973). Other very recent cones are located at the southern end of the massif, and crater lakes are also present.
The Global Volcanism Program is not aware of any Holocene eruptions from Ambre-Bobaomby. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Ambre-Bobaomby 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 cloud-covered area left of center is the Ambre volcanic massif. The broad Ambre-Bobaomby volcanic field extends from near the eastern coast (bottom) to include the Orontany Peninsula at the upper right. The north-pointing, arrow-shaped Cape Ambre peninsula forming the extreme northern tip of Madagascar lies at the lower right in this Space Shuttle view. The Ambre-Bobaomby volcanic field consists of Miocene volcanics capped by very recent cones and crater lakes.

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.
