Relief Physical features of American SamoaOfu, Manua Islands, American Samoa

Except for the coral atolls, the islands of American Samoa were formed within the past seven million years by volcanic activity; their interiors are high and rugged. The main island of Tutuila, with an area of 52 square miles (135 square km), rises steeply above deep inlets. The most notable of these inlets is Pago Pago Harbor, which divides the island nearly in two. Tutuila’s highest point is Matafao Peak (2,142 feet [653 metres]). The Manua island group (Tau, Olosega, and Ofu islands), situated about 60 miles (100 km) east of Tutuila, constitutes the second largest island area. Coral reefs are common at the extremities of the islands, particularly Tutuila; some of the reefs form barriers that enclose lagoons.

Climate

American Samoa’s climate is tropical, and precipitation is ample. Pago Pago receives about 200 inches (5,000 mm) annually. Most streams carry greater volumes of water in the highlands than near the sea and do not reach the ocean; rather, they filter into the porous basalt rocks. Hence, coastal wells provide much of the water supply. Temperatures are unusually constant; average temperatures range from the high 60s to the low 90s F (about 21 to 32 °C). Average humidity is 80 percent. The moderate southeast trade winds prevail, but severe storms can occur during the wet season, from November to March.

Plant and animal life

Rainforests with tall ferns and trees cover the mountainous interiors of the islands. Plantations of taro, coconut, and other food crops are located on the coasts. Although the islands are not rich in animal life, some of their bird species—such as the rare tooth-billed pigeon—are unique. Wildlife includes flying foxes (a type of bat), lizards, rats, snakes, and pigs. The islands also have myriad and ubiquitous flying and crawling insects.

Economy

American Samoa: Major import sourcesAmerican Samoa: Major export destinations

The economy is based on services and manufacturing. The government is the main employer. A large part of the national income comes in the form of grants from the U.S. federal government. Tuna canning (by American-owned canneries) and tourism are major industries. Agriculture is organized on a semicommercial basis for the production of taro, bananas, tropical fruits, and vegetables. Traditional family gardens produce coconuts, breadfruit, and yams. Production nearly meets domestic needs, and the U.S. government has implemented programs to increase production to self-sufficiency levels. The United States and Singapore are the main sources of imports (which include fish destined for the canneries, consumer goods, food, and mineral fuels), although Fiji and New Zealand are also notable exporters of goods to American Samoa. The United States is the primary destination for exports, which consist mostly of canned tuna, along with a small amount of pet food.

A major public works program on American Samoa from the 1970s to the ’90s increased the number of miles of paved roads, mostly on the island of Tutuila. Pago Pago is the only major port. An international airport is located on Tutuila, and smaller airstrips operate on other islands.
