Viaud Ridge is an undersea mountain range in the Indian Ocean located south of India, southwest of Sri Lanka and east of the Maldives. Its morphology remains poorly defined: estimates range from between 15 and 25 kilometers long, peaking at about 1,700 meters above the ocean floor. Discovered in 1970, it was only named in 1993 in honor of the brother of the French writer Pierre Loti, Gustave Viaud, a naval surgeon and the first photographer of Tahiti who died and was immersed in the area in 1865.
