Geography

Yap is made up of four separate islands: Yap Proper (Marbaaq, with the southern region referred to as Nimgil), Gagil-Tamil, Maap (Yapese: Maap'), and Rumung (the latter three collectively known as Marfach). The four islands are encircled by a common coral reef and are separated by relatively small water features. Gagil-Tamil and Yap Proper were once linked, but in 1901 a narrow canal called the Tagireeng Canal was built to cut the two landmasses apart.

Yap was formed from an uplift of the Philippine Sea Plate, and is referred to as a high island as opposed to atolls. The land is mostly rolling hills, with densely vegetated valleys and savanna interiors. Mangrove swamps line much of the shore, although there are beaches on the northern and western sides of the islands. Excluding the reef area, the Yap Main Islands are approximately 24 km long, 5–10 km wide, and 98 km2. The highest elevation is 178 m (584 ft) at Mount Taabiywol in Fanif municipality on Yap Proper.

Administration

Administratively, the Yap Main Islands are divided into ten municipalities that sometimes cross the water features that divide Yap into its constituent islands.
