Abstract：We use morphological analysis ,first-order difference ,vector synthesis and average rate of syn-thesis method to analyze the Yunlong station deformation data before and after the Yunlong MS 5 .0 earth-quake on May 18th 2016 ,the results show that the annual variation curve ,daily mean values and the ratio appear extremely anomalies before the MS5 .0 earthquake .The anomalies are mainly of annual variation range distortion ,daily mean value turning even annual variation breaking ,vector swerve ,and velocity changes exceed 2 times the mean variance et al .
Keywords：morphologic methoddifferential methodvector methodaverage rate synthesis methodpre-cursor anomaly
