The mutual relation and influence between the crustal deformation and the subsurface fluid are present obviously.The abnormality of crustal deformation is the most direct reflection of crustal tectonic change,and also is one of the most definite seismic precursor on physical meaning,and the anomaly of subsurface fluid can provide polytype precursory information on tectonic active process (as well as earthquake).This two types of anomaly can reflect precursory information in the development process of earthquake by different ways and features, thereforce become the important methods of seismologic prediction.In this paper,the research achievements of anomalous characteristics is summarised,the interrelation of two types of anomaly is concluded from their mechanism and precursory anomalous characteristics.
