context_page_description: Agrihan is an island in the Northern Mariana Islands in the Pacific Ocean. The island is currently uninhabited. Agrihan is located 62 kilometers to the north of Pagan.
context_section_description: Agrihan is a densely forested island, roughly elliptical in shape, with a length of 9 kilometers (5.6 mi) and a width of 6 km (3.7 mi) and an area of 44 km² (17 sq mi). The entire island is a massive stratovolcano, called Mount Agrihan, which rises over 4,000 meters (13,120 ft) from the ocean floor, and is the fifth largest in the Marianas volcanic arc. At 976.5792 m (3,204 ft), 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 500 m (1,640 ft) 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 and within the deep ravines that descend radially from the summit.
