Mount Takachiho

Kirishimayama

Shield volcano · Japan · 1700m

Takachihomine peak (center) in the Kirishima volcanic complex is flanked on the E (right) by Ohachi, with its broad summit crater. Madudake cone is to the far right. Kirishima is a large group of more than 20 Quaternary cones within Kirishima National Park, located N of Kagoshima Bay. The late-Pleistocene to Holocene group of cones, maars, and underlying shield volcanoes occupies an area of 20 x 30 km.

Geological summary

Kirishimayama is a large group of more than 20 Quaternary volcanoes located north of Kagoshima Bay. The late-Pleistocene to Holocene dominantly andesitic group consists of stratovolcanoes, pyroclastic cones, maars, and underlying shield volcanoes located over an area of 20 x 30 km. The larger stratovolcanoes are scattered throughout the field, with the centrally located Karakunidake being the highest. Onamiike and Miike, the two largest maars, are located SW of Karakunidake and at its far eastern end, respectively. Holocene eruptions have been concentrated along an E-W line of vents from Miike to Ohachi, and at Shinmoedake to the NE. Frequent small-to-moderate explosive eruptions have been recorded since the 8th century.
