%X The high-rate GPS data from 8 stations in the 2011 Mw9.0 Tohoku earthquake were processed by using precise point positioning,and the displacement time series at each GPS site were analyzed to derive displacement waveforms for this event.The results indicate that the maximum displacement of GPS stations during the earthquake is larger than the permanent deformation.The kinematic solutions show that the maximum amplitude of east and north displacement is up to 5.9 m,1.8 m respectively,and horizontal displacements were towards the epicenter on the whole.At last,the epicenter and the S wave velocity is derived from the arrival time recorded by the GPS stations in the region.
