Weathering of volcanic ash deposits can produce rich volcanic soils that are fertile nutrients for agriculture, such as these fields at the foot of Kaimon volcano in southern Kyushu. It is no accident that population density is high near volcanoes--although volcanic ash soils underlie less than 1% of the Earth's land surface, they support 10% of the world's population. Volcanic soils support crops such as rice fields in Indonesia, the Philippines, and Japan, sugar cane in Hawaii and Central America, and vineyards in Italy.

Symmetrical Kaimon volcano is the youngest and most prominent feature of the Ibusuki volcanic field at the southern tip of Kyushu. The 922-m-high stratovolcano, seen here from the north, was built during the last 4000 years and has produced all the historical eruptions of the volcanic field. The Ibusuki field, located west of the Pleistocene Ata caldera, contains numerous small central cones, maars, and the 4.5-km-wide Ikedo-ko caldera. The latest eruptions of Kaimon took place during the 9th century.

Ikeda-ko, a 4.5-km-wide, lake-filled caldera, was formed as a result of a major explosive eruption about 4600 years ago. Kaimon volcano, the highest peak of the Ibusuki volcanic field, rises to the SW above the caldera rim. The eruption of the 3 cu km Ikeda pumice was the the largest Holocene eruption of the Ibusuki volcanic field, which consists of a group of small central volcanoes and maars, along with Ikeda-ko caldera and Kaimon stratovolcano.
