Abstract On the basis of seismic waveform and phase arrival time data, by accurately locating and normalizing the position of clustered earthquakes, the crustal medium microdynamic change in the placebonder on JiLuYu 3 provinces were given. The results show that the moving averages of Pwave traveltime appears negalively anomalous in medium and short terms before moderate earthquakes, i.e. the travelvelocity of crustal media raised. It means that the artesian conditions of crustal medium in different directions can be different from each other.
