Yap

Yap or Wa′ab (Yapese: Waqab) classically refers to an island—the Yap Main Islands—located in the Caroline Islands of the western Pacific Ocean, and a part of the Federated States of Micronesia. The name "Yap" in recent years has come to also refer to the state within the Federated States of Micronesia, inclusive of the Yap Main Islands and its various outer islands.

The Yap Main Islands is considered to be made up of four separate islands: Yap Island proper (Marbaq), Gagil-Tamil, Maap (Yapese: Maap′), and Rumung. The four are contiguous, though separated by water and are surrounded by a common coral reef. They are formed from an uplift of the Philippine Sea Plate, and are referred to as "high" islands as opposed to atolls. The land is mostly rolling hills, densely vegetated. Mangrove swamps line much of the shore, although there are beaches on the northern sides of the islands. Yap's indigenous cultures and traditions are strong compared to other states in Micronesia.

Colonia is the capital of the State of Yap which includes the Yap Main Islands and the Yap Neighboring Islands—the outer islands (mostly atolls) reaching to the east and south from the Yap Main Islands for some 800 km (500 mi), namely the atolls of Eauripik, Elato, Faraulep, Gaferut, Ifalik, Lamotrek, Ngulu, Olimarao, Piagailoe (West Fayu), Pikelot, Sorol, Ulithi, and Woleai, as well as the islands of Fais and Satawal (see map). Historically, a tributary system existed between the Neighboring Islands and the Yap Main Islands. This probably related to the need for goods from the high islands, including food, as well as wood for construction of seagoing vessels.
