Abstract: The uniform resolving was carried out under the frame of ITRF2005 with the observation data of pre-earthquake, mid-earthquake and 10 months after the earthquake from 12 sites of JSCORS network, using IGS precision ephemeris, and taking several IGS standard stations at at home and abroad as control reference. The result of resolving suggested that from 1 to 2 hours after the earthquake the horizontal displacement of JSCORS sites far from 1500km of the epicenter was appeared, whose amplitude was related to the geological conditions of them, and that 10 months after the earthquake the variation of horizontal displacement was less than 8 mm. Considering the measuring error, it can be thought that the remarkable ground horizontal displacement of Jiangsu Province didn’t happen in the medium-short term after the earthquake.
