Abstract：Fixed-point deformation is an important precursor observation method.This article summarized the anomalies of fixed-point deformation groups that have occurred in Yunnan Province since 2019 and analyzed the characteristics of the anomalies as follows:The anomalies are distributed in various stations,with significant amplitude,synchronous time,and long duration.Based on the analysis and discussion of the characteristics of seismic activities,it is believed that there is a certain consistency between group anomalies and seismic activities,which has reference significance for future seismic situation analysis and judgment in Yunnan.
