Abstract：The Hori and YabukiMatu’ura inverse methods are used to estimate the distribution of interseismic slip deficit on the border land between Philippine Sea plate and the southwest Japan with GPS data from Jan.,1997 to Dec.,1999. The estimated results show that maximum slip rate is about 7 cm/a, which is consistent with the Philippine Sea plate convergence rate. The 50% contribution of strong coupling is confined to the depths of 10-30 km. By compring the two results it can be seen that there are some different effects caused by the collision between eastern and central Japan, because of different analytic process and constrain condition. It can be concluded that Hori inverse method is more applicable and impersonal to estimate slip distribution in the area with dense observation networks, such as the southwest Japan.
