  • By calculating GPS observation data from some fiducial stations in CMONOC each year be-fore and after the Tohoku-Oki earthquake,time series and velocity data from these fiducial stationsobtained.On this basis,this paper discusses the impact of the Tohoku-Oki earthquake on the fiducialstations on a longer time scale.This research shows that as compared to the velocity before the earth-quake,the fiducial stations in northeast China near the epicenter had a accelerating trend,and themovement direction tended towards the epicenter,while the movement velocity and direction of the fi-
