The Ankaizina volcanic field, covering portions of the Tsaratanana and Ambondrona massifs in northern Madagascar, was active until the very recent Quaternary. An initial dominantly silicic phase included pyroclastic-flow formation and was accompanied by the emission of minor basaltic lava flows. An earlier now-eroded basaltic phase was followed by the most recent activity, which produced a series of perfectly preserved cinder cones and lava flows that traveled down current valley floors in the Bealanana region.

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

The Global Volcanism Program has no synonyms or subfeatures listed for Ankaizina Field.

The Global Volcanism Program has no photographs available for Ankaizina Field.

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.
