Abstract:: The purpose of this paper is to explain the annual variation characteristics of the lithospheric magnetic field before the Yangbi M_S6.4 earthquake with the meta-instability theory.The spatial distribution characteristics year by year of the horizontal vector of lithospheric magnetic field in Yunnan province from 2017 to 2021 before the Yangbi M_S6.4 earthquake is reviewed and compared with the process of steady state-met-astable state-meta-instability state-instability state.The results show that the weakening region of the horizontal vector in the meta-instability O stage is the most easily recognized typical mark in field observation; There are “overlapping” zones in the weakening region for two consecutive periods or more,and the outer horizontal vector increase and change their direction.These mark the “irreversible” meta-instability OB stage,which indicates that the earthquake will occur at the edge of the “overlapping” region.It is a meaningful attempt to change the study of meta-instability theory from laboratory to field observation in addition.
