Alifushi and Etthingili (Powell Islands in the Admiralty Chart) stand on a detached reef of their own with very deep waters (no sounding) between this faru and the northern end of the main atoll.
Its western fringe is composed of a series of round or oval reefs (farus) irregularly placed (a feature peculiar to all the larger Northern Atolls).
The centre is heavily dotted with coral patches (giri), some submerged and some awash.
The concentration of giri is especially dense towards its SW quarter, close to Kandholhudhu Island (where there is the place most crowded with small reefs and shoals in the whole Maldives), but its narrower northern end is quite clear of reefs.
Recently, the island has been reclaimed up to the edge of the reef in order to provide land for social and economic activities for the growing population.
On 17 October 1968 after people of Ufulandhoo transferred to Alifushi, they asked the government for permission to be relocated to Maduvvari.
The project of relocating the two island people to Hulhudhuffaaru started in 1992 and completed on 13 March 1993.
[1] Alifushi, located at the northern end of the atoll, is an island which has been traditionally famous for its skilled boatbuilding carpenters.
