AbstractA Mw 9.0 earthquake occurred in the Tohoku-Oki of Japan in 2011. The coseismal deformation observation from GPS and InSAR meanings were used to inverse the slip distribution of the earthquake. Firstly, six ascending ALOS/PALSAR tracks and three descending Envisat/ASAR tracks that cover most of northeastern Japan were processing by two-pass interferometric synthetic aperture radar (InSAR) to obtain acoseismic deformation results, which are calibrated by GPS data. Secondly, the rectangle dislocation models in elastic half-space were used to derive the kinematic characteristic of the earthquake fault combining with GPS and InSAR data. The inversion result indicates that the fault slip concentrates mainly in the depth between 40 km and 50 km, the maximum slip is about 50.3 m, the geodetic moment is 3.197×1022 N\5m(Mw 8.94).
