| 摘 要： | 应用CH方法对新疆境内21次MS6.0以上地震前显著地震特征进行了回顾性研究。 研究结果显示, 21次强震中, 有10次强震前出现2个以上显著地震, 其中满足CH判据的地震有7次, 占显著地震个数满足CH方法地震数的70%。 7次满足CH判据的地震中, 除1973年精河6.0级地震发生在其显著地震后63天外, 其余主震都发生在其满足条件的显著地震后25天以内。 结果表明, CH方法可应用于新疆强震前的短临预测。

| Abstract: | Authors used the CH method to study the significant earthquakes before 21 strong earthquakes with MS6. 0 in Xinjiang. The study show that, of 21 strong earthquakes, there are 10 strong earthquakes, before which occurred more than 2 significant earthquakes, and 7 strong earthquakes meet the CH criterion, accounting for 70% of the earthquakes, whose number of significant earthquakes meet the CH method. Of the 7 earthquakes, the main earthquakes occurred 25 days later after its significant earthquakes, excepting the Jinghe M6.0 earthquakes occurred 63 days later after its significant earthquakes. The result shows that CH method can be used for the short-term earthquake prediction before strong earthquakes in Xinjiang. |
