Summary: The history of the vertical crustal movements of Northeast Japan since Middle Miocene (16 m.y.B.P.) has been examined quantitatively. The movements of the western zone (inner arc) and those of the eastern zone (outer arc) are different. The western zone subsided during the period from 16 to 10 m.y.B.P. and then was uplifted during the subsequent period, the rate of uplift being enhanced during Quaternary time. The eastern zone, east of the Backbone Range, has been uplifted throughout the period. These results have been interpreted in terms of the change in the mode of subduction from the Mariana-type to the Chilean-type. Recent discoveries on the vertical movement in the fore-arc region of the Japan Trench, showing that Neogene subsidence has been followed by Quaternary uplift, have also been incorporated into this history.
