The Union of the Comoros is a volcanic archipelago located in the Indian Ocean, off the eastern coast of Africa, between northern Madagascar and the eastern coast of Mozambique. The archipelago consists of three main islands: Grande Comore (Ngazidja), Mohéli (Mwali), and Anjouan (Ndzuwani), along with numerous smaller islets. Each island is distinct in its geological formation, but all are of volcanic origin, giving rise to dramatic landscapes ranging from towering mountains to lush tropical forests and pristine beaches. The islands are characterized by rugged coastlines, active and dormant volcanoes, crater lakes, and coral reefs that support a diverse range of marine life. The climate is tropical, with warm temperatures year-round and significant rainfall, supporting rich biodiversity, both terrestrial and marine.
Due to its volcanic origins, the geography of Comoros is rugged, with numerous mountains and fertile soils, making the islands lush and green. The country’s ecosystems include rainforests, coastal mangroves, and coral reefs, which are home to many endemic species.
