lurid accusations. The story was revived in 1998 by Japanese author Kaoru Ohno as the novel Cage on the Sea, and in 2008 by Natsuo Kirino as the short story "Tokyo-jima", which became a film in 2010. Following World War II, the island came under the control of the United States and was administered as part of the Trust Territory of the Pacific Islands. Since 1978, the island has been part of the Northern Islands Municipality of the Commonwealth of the Northern Mariana Islands. Geography Anatahan is roughly elliptical in shape, with a length of and a width of and an area of . The island is the summit of stratovolcano which reaches an altitude of above sea level at its highest peak. The volcano is topped by a caldera, wide, which is divided into an eastern and western portion, with the eastern portion around lower than the western. Sparseness of vegetation in the most recent lava flows on Anatahan indicated that they were of Holocene age. In April 1990, the inhabitants of the western coast of the island were evacuated after earthquake swarms and active fumaroles indicated that an eruption might be imminent, but no eruption occurred at that time. A further earthquake swarm occurred in May 1992. The first historical eruption of Anatahan occurred in May 2003, when a large explosive eruption with a VEI of 4 took place forming a new crater inside the eastern caldera and causing an ash plume high which impaired air traffic to Saipan and Guam. The most recent eruption was in 2007, and lasted until 2008. Demographics As of 1980 the population of Anatahan was one family. The people resided on Anatahan when school was not in session.
