The Federated States of Micronesia are made up of four island groups - Yap, Chuuk, Pohnpei and Kosrae - located in the eastern half of the Pacific Ocean. They're roughly 3000 miles (5000km) west of Hawaii, lying just above the Equator. The four states are actually grouping of 607 small islands and atolls. Generally speaking, the FSM comprises what is known as the Eastern and Western Caroline Islands.
While the country's total land area amounts to only 270.8 square miles, it occupies more than one million square miles of the Pacific Ocean, and ranges 1,700 miles from East (Kosrae) to West (Yap). Each of the four States centers around one or more "high islands," and all but Kosrae include numerous atolls. Chuuk State has a total land area of 49.2 square miles and includes seven major island groups.
Dives Not To Miss: A whole Japanese fleet rests on Chuuk or Truk lagoon floor, evidence of the largest naval loss in history. They are the Fujikawa Maru, Shinkoku Maru, San Francisco Maru, Nippo Maru and Sankisan Maru.
