Yunnan is one of the main seismic activity areas in China.It lies close to the subduction zone where the Indian plate moves towards the Eurasian plate and belongs to the southern section of the north-south seismic belt in China.Historical earthquake activity in this area shows that earthquakes of high frequency and large magnitude occur.The Yunnan region and its adjacent areas are ideal locations for the study of seismicity.Existing research shows that regional seismic activity is closely related to gravity field changes that are mainly caused by geological activities such as crustal deformation and fault material change.Such changes reflect crustal movement and the associated processes involved in large earthquakes.Therefore,gravity changes can be used to predict earthquakes.The GRACE (Gravity Recovery and Climate Experiment) binary star system,jointly developed by NASA and the DLR,provides a time-varying gravity field and thus important information for the exploration of Earth's interior materials.GRACE satellite observations clearly reflect the motion of the Earth's plates and expand the scope of gravity anomaly seismic observations that can be used for long-term forecasts of earthquakes.In this paper,we use gravity field data from GRACE satellites to calculate and analyze the satellite gravity field variation characteristics from 2003 to 2014 in the Yunnan region and its adjacent areas.We also obtained the monthly gravity change sequence of three feature points,and in this study we analyze their change characteristics by combining the distribution of M≥5 earthquakes from 2003 to 2014 in the study area.Results show that the M_S≥5 earthquakes in the Yunnan region and adjacent areas are reflected in satellite images of gravity field changes,and that large earthquakes often occur on the high gradient zone of regional gravity changes.The earthquake zone often shows a corresponding change in satellite gravity characteristics both before and after large earthquakes,which may reflect crust-mantle material adjustment.The corresponding earthquake gravity change characteristics of the three points are different,which may indicate that research into the gravity field changes in various regions and faults is significant for earthquake prediction.
