Abstract:The history,current situation of the research on dislocation theory and its contribution to seismology and geodesy,especially,the latest research achievement of the dislocation theory of spherically symmetric and 3D spherical earth models and concerned gravity changes are described in brief.In addition,the computation method and possible problems in the application of dislocation theory to the analysis of the observations of gravity satellite are discussed.Through some observational instances the progress and important achievement in the research on the theory and observation of the gravity change caused by seismicity and vilcanism are intorduced.
