摘要
Selecting a great deal data of short-impending and impending earthquake precursory,and citing the recordings of the observational long-period deformation wave,we overview the research on the long-period deformation wave.Then we analyze the feature,shape and amplitudes of the anomalous images of the deformation wave of some typical earthquakes recorded by tidal deformation instruments before and after the earthquake to study the features of the long-period wave—duration of anomaly,effective monitoring rang,main shock magnitude range,anomaly shapes,period and propagation velocity.The results show that the duration of deformation anomaly extends from several hours to 6.5 days.The magnitude of the predicted earthquake is greater than 6.0 and the effective distance range is from 100 km to 2 000 km.
