| 摘 要： | 本文对新疆1978年4月22日库尔勒5.8级地震前地震波的动力学特性和运动学特性的某些短期变化进行了初步研究。重点讨论了5.8级地震前通过孕震区的小地震的直达波振幅比、振动持续时间比以及波速比的短期异常变化,並且,结合震前短期地震活动异常图象作了对比分析。实际观测结果表明,较大地震发生前,通过孕震区的小震的地震波特性可能出现一些较明显的短期异常变化,因而,对此进行研究无疑对于探讨地震孕育过程和地震的预报途径都是有意义的。

| Abstract: | 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. |
