【摘要】 分析了乌什-阿图什地震危险区所处的柯坪块体地震时空活动特点:6级以上地震均沿块体边缘分布;6级地震时序分布不均匀,空间分布表现出轮回特征;6级地震前4级地震平静较为普遍,相关构造带以增强-平静为主要特征;响应地震的地点指示意义较为明确。文中还对危险区异常判定及2009年块体3次5级地震异常跟踪进行了总结。更多还原

【Abstract】 This paper analyzed the spatial and temporal feature of earthquakes in Keping block located in the Wushi-Atushi seismic dangerous region.The result showed that the earthquakes with MS≥ 6 were distributed on the edge of the Keping block and had the spatial transmigration and uneven timing distribution feature.The MS4 earthquakes appeared quiet before the MS6 earthquakes,the seismicity in the related tectonic zone was characteristiced of activityquiescence.The response earthquakes indicated the possible location of future moderate earthquakes.The article summarized the seismic dangerous region judgment and seismic anomaly tracing of 3 MS5 earthquakes in the Keping block in 2009.更多还原
