In this paper, we make a preliminary analysis of certain short-term anomalous variations of the kinematics and dynamies of seismic wave before the Xinjiang Kuerle earthquake(M=5.8, April 22, 1958).
Using the amplitude ratio s of p and waves, duration ratio, anomalies of the seismic vilocity in the anomalous regions microearthquakes are discussed.
The results from the observational data show that there are clear anomalous variations of the characteristics of seismic wave before the strong earthquake. Therefore, to study of characteristics of seismic wave may be helpful for understanding the physical process of source and prediction of the strong earthquake.
