| 摘 要： | 对尼勒克、巩留交界MS6.0地震序列特征、震源机制以及震前震中周围地区地震活动图像异常特征等进行了分析。结果认为,本次地震序列为主-余型,震源机制为逆断型,发震构造为阿吾拉勒山南缘断裂。震前中期阶段存在4级地震空区、4级地震条带、小震群累积月频次和地震活动性参数等异常;短期异常出现了3级地震空区、3级地震平静、地震窗和地震波振幅比等异常。此次地震前出现的部分异常与2007年特克斯5.9级地震前的地震活动异常图像具有类似特征。

| Abstract: | According to sequences characteristics、focal mechanism solutions and anomaly seismic activities of Nilke、Gongliu earthquake,it belongs to main shock-after shock type and seismogenic structure was southern margin of Awulale mountain.Anomaly phenomenon such as seismic seismic gap、seismic belt、earthquake sequence monthly frequency and seismic activity parameters of earthquake with MS4.0 appeared in the mid-term stage;seismic gap、seismic quiescence、seismic window and amplitude ratio of earthquakes with MS3.0 appeared in short-term.Part of anomaly image is similar to Tekes earthquake with MS5.9,2007. |
