Abstract Based on continuous observation data of GNSS in Yunnan since 2014, the velocity and strain parameters are solved by least squares configuration and the Kriging interpolation method. The velocity field and strain field results are used to analyze recent crust activity features of Yunnan region, as well as the resulting influences on strong earthquakes. The results show that the velocity field, based on Wenshan measurement point, show a whole clockwise motion characteristic, and the direction of motion is different. The maximum shear strain accumulation in the whole area of Yunnan is fastest and strongest in northwestern Yunnan, and the squeezing strain accumulates in south and southwestern Yunnan. In the year 2014, the strong earthquakes of magnitude 6 and above have maintained a good consistency with the maximum shear strain in the macroscopic direction, and the occurrence of the earthquake does not change the stress and strain distribution pattern and growth trend of the whole area in Yunnan.
