Tutuila & Aunu’u Islands

Tutuila & Aunu’u Islands

Tutuila is the largest and the main island of American Samoa in the archipelago of the Samoan Islands. It is the third largest island in the Samoan Islands chain. Tutuila is a fairly small and narrow island, measuring roughly 25 miles across and little more than 3 miles from north to south at its widest point. The area of this volcanic island, of early Pliocene Age, is 54.9 square miles with a shoreline of 62.9 miles. The mountain range, which runs from west to east, is rugged and winding with the northern coastline having steep cliffs and unusual coastline. However, the southern part of the island has flatter terrain. The highest point in the Tutuila Islands is the Matafao Peak, which is at an elevation of 2,142 ft.

Aunu’u is a small volcanic island off the southeastern shore of Tutuila. It has a land area of a half square miles and features the Faimulivai Marsh, a freshwater marsh in the Aunu’u Crater and the largest such wetland in American Samoa. It was formed from drainage of the low-lying crater and is a protected National Natural Landmark which was designated in 1972.
