| 摘 要： | 分析了１９９６年３月１９日新疆阿图什ＭＳ６．９地震前几种地震波参数的异常特征。该次地震前初动符号、振幅比、尾波衰减系数、尾波持续时间比均有不同程度的异常，地震活动空间图象、时序曲线也存在一定的异常。根据上述异常作者对该次地震作出了短临预报，预报三要素与实际地震相符。介绍了预报思路和方法，并对异常机理进行了初步分析

| Abstract: | In this paper,the anomalous characteristics of some seismic wave parameters before the Atushi M S 6.9 earthquake in Xinjiang on March 19,1996 have been analyzed.Some seismic wave parameters such as the first motion mark of seismic wave,amplitude ratio,attenuation coefficient of coda and duration ratio of coda showed anomaly in varying degree before this earthquake.There were also certain anomalies in spatial picture and time sequence curve of seismic activity.The wri ter made a short impending term forecast for this earthquake based on above anomalies and three factors of prediction corresponded to the actual situation.The prediction thinking and method have been introduced and the anomaly mechanism is initialy analyzed also. |
