Abstract:By processing the observation data of the GPS network in Chongqing from February,2008 to October,2010, the following data were obtained: the coseismic displacement of 12 GPS stations in this area, the time series of crossfault baseline length before and after Wenchuan earthquake, the horizontal movement field of Chongqing GPS stations related to WUHN and the horizontal movement rates of Chongqing under the regional NNR frame. The results show that the maximum of the coseismic horizontal displacement in Chongqing is 24 mm, and the minimum is 7 mm.After that event, the crustal movement in Chongqing has been steady as a whole.
