There are no Holocene eruptions known for Nosy-Be. If this volcano has had large eruptions prior to 10,000 years ago, information might be found in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. 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. Additional discussion of data sources can be found under Volcano Data Criteria.

Nosy-Be island off the NW coast of Madagascar contains very recent basaltic lava flows from well-preserved cinder cones. Many large crater lakes are found in the central part of the island. Nosy-Be volcanics, which are dominantly of low-silica foiditic compositions, overlie Mesozoic limestones and other sedimentary rocks. Two periods of activity occurred at Nosy-Be. Initial eruptions of fluid lava flows from the western side of the massif were followed by the construction of numerous strombolian cinder cones on the western plain. Little is known about the age of the volcanic field, and the only K-Ar dates are Tertiary in age, but the Nosy-Be volcanics were mapped as Recent (Besairie, 1973).
