对强震孕育和发震期阿拉木图预报试验场弱震活动性进行了动力学分析,发现弱震活动性变化明显地表现出时空平静异常。研讨了北天山地震平静异常表现的形态和幅度特性。
The dynamic analysis of the weak earthquakes in the Alma-Ata forecast test ground during the period of strong earthquakes and earthquake occurrence shows that the changes of weak earthquakes obviously show the time-space calm anomaly. The morphological and amplitude characteristics of the anomalous seismic anomalies in the North Tianshan Mountains are discussed.
