Abstract：In order to study the crustal movement of Shandong and surrounding areas before and after Wenchuan \%M\%s8.0 earthquake, we analyzed the baselines between Taian(TAIN) and several fiducial stations in different blocks by using SDFT Period Estimate method. The preliminary results showed that there were obvious exceptional annual variations of baseline TAINXIAN and TAINWUHN before Wenchuan earthquake. The eastward movement velocity of GPS fiducial stations in Shandong and surrounding area was decreasing after the earthquake, we conclude that the eastward driving force on the North China block weakened, It shows that the Wenchuan earthquake alleviated the Shandong and surrounding areas’ recent earthquake situation.
