Geyser is a reef located 110 km northeast of Mayotte and 122 km southwest of the Glorious Islands, as well as 300 km west of Madagascar's northern tip. The bank dominates the 3,500 m deep abyssal bottoms that separates it from Mayotte.
In the shape of a crescent, with its points facing west, Geyser Bank only emerged at low tide, with the exception of a few rocks to the south.
It is approximately 8 km long, its oval is about 5 km wide and occupies an area of 175 sqkm. The largest rock in the southern part rises to nearly 8 m, the others from 1 to 3 m and has some grasses and shrubs.
The Geyser Bank is a recognised scuba diving and fishing site. Humpback whales stay there during the southern winter. We can see mothers with their calves. However, this activity is subject to the control and authorisation of the administration of the French Southern and Antarctic Territories. Several foreign recreational vessels were arrested on this occasion and their diving equipment seized by the French Navy.
This reef, which must be more than 15 million years old, is very dangerous for navigation. It was discovered by the Arabs around 700 and has been represented on maps since about 800 AD. The Spanish rediscovered the reef around 1650 and called it "Arecife de Santo Antonio". The captain of the British ship Geyser gave the name of his ship to this reef on 23 December 1678.
From the French point of view, this reef is part of the Scattered Islands of the Indian Ocean (and administratively linked with them in the Fifth District of the French Southern and Antarctic Territories) and extends the French Exclusive Economic Zone of the Indian Ocean (which can extend 200 miles or 370.4 km from the baseline). Many pirate fishing vessels have been boarded in the area.
