Ankaizina Field
"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."  -Smithsonian Volcano Archive
