Relation between Crustal Structures and Crustal Movements in Japan

Abstract

As the present crustal structures have been formed by the tectonic movements through the long geological age, problems of the crustal movements must be studied in connection with the information of the present crustal structures obtained from geological, geomorphological and geophysical methods. In this paper, the relation between the crustal structures and the crustal movements in Japanese islands found by geodetic methods is investigated from the following three points.
1) The relation between the changes of the intensity of crustal movements with time and those in space.
2) The relation between the horizontal variations of the crustal movements and crustal structures.
3) The difference of the characteristics of the crustal movements in orogenic regions (Japanese islands) and in continental platform.
