Banc Vailheu, north-west of Grande Comore, is within 7 m of the surface at low tide. It is quickly reaching surface point and may one day become a volcanic Island or drying sand cay.
Arguably, the Glorioso islands, under French administration, are counted as being part of the archipelago. They were administered by the Comoros before 1975, and are therefore sometimes counted.
The Union of Comoros is recognized as including the three northernmost islands. Anjouan and Mohéli declared their independence in 1997, however these unilateral declarations of independence received no international recognition and were later rescinded.
Ngazidja is the youngest of the islands, and has a massive active volcano on it, which scientists are afraid will erupt in the near future.
