Based on processing the data which were recorded by GNSS continuous observation stations in Yunnan Province by deducting intro-regional stable reference point, sliding mean value etc. , we obtained timing dia- gram of regional deformation field movement rate of Yunnan Province, and analyzed the relationship between crustal movement and the seismic events occurred during this period. The analysis results showed that movement direction of some points deviated away from crust movement background in the long trend, earthquake was more likely to occur in Yunnan. This research made an exploration for GNSS continuous observation data used in earthquake prediction and forecasting.
