利用地震波参数辨析地震异常

通过对库尔勒、阳霞一线1987年11月至1988年12月S-P≤28秒的地震记录进行分析,发现:1988年5月26日库尔勒Ms5.2级地震前,该区P波初动一致性分析、振幅比、尾波持续时间比、尾波衰减系数、S波分裂等项测震学手段均出现不同程度的异常。这表明,利用地震波参数对重点地震监视区进行短、临动态跟踪,有可能成为解决地震预报问题的有效途径。

USING THE PARAMETER OF SEISMIC WAVE TO RESOLVE THE ABNORMAL PATTERNS OF EARTHQUAKES

After analyzing the seismic recordings for S-P^.2B seconds during Nov. 1987-Dec. 1988along Korla and Yangxia region ,the author found out that just before Koral Ms 5. 2 earthquake on May 26, 1988,several monitoring methods such as coherent analysis on the primary wave , rate of amplitude ,rate of coda duration ,coda attenuation coefficience and surface wave separation showed some anomalies . It is suggested that by using the parameter of seismic wave to trace the short term and impending anomalies in the principle monitoring areas can we find an effective way to earthquake prediction.
