compression axis. The dilatation map shows a compression state zone that spread along Shikoku Island toward the central-east of Kyushu Island. The maximum rate of negative dilatation, compression state, in the southwest of Shikoku Island with the direction of NNW, is 0.19 – ۰٫۲۱٫strain / yr that delineate the subduction effect of Philippine Sea plate under the Amurian plate. On the other hand, in the southwest of Kyushu Island the positive dilatation, extensional state, with the rate of 0.05 – ۰٫۰۷٫strain / yr and with the direction of NW-SE is dominant and can explain the opening feature of the northern tip of the Okinawa trough in the western off this area.
