Shinmoedake (Japan)

Status Unrest Eruption 2018 1700m
Shield (Subduction zone / Continental crust (> 25 km))

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.

Sharp-peaked Takachiho-mine (center) is the 2nd highest peak of the Kirishima volcanic complex. It is flanked on the east (right) by Ohachi, with its broad summit crater. Madu-dake is the grass-covered cone at the far right. Kirishima is a large group of more than 20 Quaternary volcanoes that is the centerpiece of Kirishima National Park, located north of Kagoshima Bay. The late-Pleistocene to Holocene group of stratovolcanoes, pyroclastic cones, maars, and underlying shield volcanoes occupies an area of 20 x 30 km.
