ResumoThis chapter describes the geology and hydrogeology of Nauru Island. Nauru is located at the southern end of the Nauru Basin, an ocean basin, 4-5 km deep, which extends from the Marshall and Gilbert Islands in the northeast to the Ontong Java Plateau in the southwest. Nauru is an independent country, with a population of 10,000 who live around the coastline. The interior of the island has been mined for its surficial phosphate deposits for about 90 years. The current phosphate reserves indicate that the mine has only a few years life left at present production rates. About 80% of the land area is denuded of its vegetation and soil cover by mining. Rehabilitation works are proposed by the Nauru government, and the financing of these works is the subject of international litigation. Nauru is hot and humid throughout the year. Rainfall records are available for Nauru for 67 years, although there are significant gaps with no information.
