| Research Abstract |
The study investigates the past 0.1Ma tephrostratigrapy of Kirishima, Aso, and Kuju Volcanoes. the Miyazaki plain in southern Japan. Their high-precision explosive eruptive histories are reconstructed on the basis of the tephrochronology. Kirishima and Aso Volcanoes have characters that the volcanic edifices are stratovolcanoes or large cinder cones with tephra-forming eruptions. Kuju Volcano has been forming mainly lava domes, while the large-scale plinian and pyroclastic flow eruptions occurred at 0.5ka. Though the magma discharge rate of Aso is degreasing recently, during the past 0.5Ma, Kirishima and Kuju have the increasing rates, that show the possibility of some large-scale eruption in near feature.
