The Global Volcanism Program has no activity reports for Nosy-Be.
The Global Volcanism Program has no Weekly Reports available for Nosy-Be.
The Global Volcanism Program has no Bulletin Reports available for Nosy-Be.
The Global Volcanism Program is not aware of any Holocene eruptions from Nosy-Be. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Nosy-Be 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.
|Cinder cones line the shores of Nosy-Be island off the NW coast of Madagascar. The youthful-looking cones have produced very recent basaltic lava flows. Many large crater lakes are found in the central part of the island. Nosy-Be volcanics 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.

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.

|WOVOdat||WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
