American Samoa lies in the Pacific Ocean approximately 3,700km (2,300 miles) southwest of Hawaii. It comprises seven islands: Tutuila, the largest with an area of 137 sq km (53 sq miles); Ofu, Olosega and Ta'u, known as the Manu'a group; and Aunu'u, Rose and Swain's. The Manu'a group is volcanic in origin and dominated by high peaks. Rose and Swain's Islands are uninhabited coral atolls, located to the east and north, respectively, of the other two island groups.
