| Abstract: | By processing the observation data of the GNSS reference station near the epicenter of the MS6.4 earthquake in Yangbi, Yunnan on May 21, 2021, three days before and after the earthquake, we analyze the impact of the earthquake on the coordinate stability of the reference station in a short period of time. According to the dynamic PPP and high-precision static data processing results, the analysis shows that the area near the epicenter of the Yangbi earthquake have significant displacements towards the southeast, the maximum displacement of the stations is about 4.8 cm, showing the characteristics of right-handed strike slip movement. |
