Abstract：The data of 26 channel watertube tilter and extensometer at 6 permanent stations located around the epicenter of 2013 MinxianZhangxian earthquake with Ms 6.6 during the period of January 1，2009 and July 21，2013（one day before the MinxianZhangxian earthquake）were analyzed.The raw data were preprocessed and tidal analyzed，and the quality of the observation was estimated.The tidal response parameters and the smoothed day averaged value were obtained.The relationship between dynamic characteristics of the deformation rates and the earthquake were discussed.
