The U.S. Territory of American Samoa is the United States' southernmost territory. American Samoa consists of five volcanic islands and two atolls (Rose Atoll and Swains Island) and is located in the central South Pacific Ocean, approximately 2610 miles (4,200 km) south of the Main Hawaiian Islands. The five volcanic islands, Tutuila, Aunu'u, Ofu, Olosega, and Ta'u, are the major inhabited islands. Tutuila is the largest island and the center of government. Ofu, Olosega, and Ta'u are collectively referred to as the Manu'a Islands.
These islands are small, ranging in size from Tutuila (53 mi or 138 km²) to the uninhabited and remote Rose Atoll (1.5 mi or 4 km²). Swains Island (approximately 0.7 mi or 2 km²) is an unbroken circle of land with an enclosed lagoon. The limited shallow water coral reef habitats surrounding all of the islands consist primarily of fringing coral reefs, a few offshore banks, and two atolls.
Many species of Indo-Pacific corals, other invertebrates, and fishes are members of the American Samoa coral reef ecosystem. Although the corals have largely recovered from a number of natural disturbances, including a major crown-of-thorns starfish invasion, several mass bleaching events, and powerful damaging cyclones, maintaining the health of the ecosystem is an ongoing task. Harmful fishing practices, coastal construction, pollution, coral bleaching, and invasive algal outbreaks have taken their toll. Management actions such as regulating SCUBA spearfishing, protecting large reef species, and relocation of tuna cannery outfall pipes have worked to mitigate some of the impacts and protect the coral ecosystem.
