    • Abstract
  • The coseismic displacements of Mw9.0 Tohoku-Oki earthquake was analyzed with some GPS fiducial stations located in China east coasts,which using epoch-by-epoch PPP and sidereal filtering technique.The result shows an apparent displacement along horizontal and vertical directions,whose amplitude is about 10 cm.However,after the earthquake,there is no obvious permanent displacements more than 1 cm,which agrees with the results of the domestic and foreign relevant groups,and proves the effectiveness of PPP technology used for coseismic displacements analysis.
