==Geography==
Agrihan is a densely forested island, roughly elliptical in shape, with a length of and a width of and an area of . The entire island is a massive stratovolcano which rises over from the ocean floor, and is the fifth largest in the Marianas volcanic arc. At , its summit is the highest point in Micronesia. The volcano is topped by a large caldera, 1 x 2 km (0.6 x 1.2 mi) in size and about deep.〔 The caldera floor has several lava flows and two volcanic cones, which were probably created during the April 1917 eruption. The only relatively flat land on the island is along the southeast shoreline and on the north side of the central caldera.
Vegetation includes Swordgrass ''(Miscanthus floridulus)'' grasslands on the upper slopes, forests of Coconut Palm ''(Cocos nucifera),'' with some Breadfruit ''(Artocarpus altilis)'' and Papaya ''(Carica papaya)'' on the lower slopes within the deep ravines that descend radially from the summit.
