Abstract:

The Union of Comoros, a volcanic archipelago located in the Mozambique Channel, is characterized by geological formations dominated by alkaline basalts, reflecting a complex magmatic and tectonic history. This study presents an integrated approach to the geology of the islands, highlighting their volcanic structures, mineral potential, major geohazards, and geological heritage. The identified resources include construction materials, strategic minerals, and significant geothermal potential. The islands are exposed to various natural hazards, including volcanic eruptions, landslides, erosion, and flooding, emphasizing the need for appropriate prevention measures. Moreover, emblematic geosites such as «Lac Salé,» the Dragon’s Back (le Dos du Dragon), and the Bambao Cirque (le cirque de Bambao) illustrate the scientific and touristic richness of the Comorian volcanic heritage. These findings provide a foundation for sustainable resource management and territorial valorization.

Keywords:
