北京地区八宝山-黄庄-高丽营断裂的活动与地震
|
摘要
根据八宝山-黄庄-高丽营断裂第四纪地质构造活动特征和利用首都圈地区跨断层位移最新的观测资料求得的北京地区区域主压应力方向和区域构造活动特征,分析了八宝山-黄庄-高丽营断裂上7处跨断层位移测点的断层活动与地震活动的关系,得出了首都圈及邻近地区即将进入下一个地震活跃期的结论。认为:1)跨断层位移观测资料能够直接反映区内主要断层的最新活动情况;2)断层现今活动与地震活动在时间序列上相互对应,均有活跃期与平静期相互交替出现的活动特征;3)断层活动强弱是区域主压应力强弱的表现,亦是孕震强度的标志。
Based on the characteristics of the Quaternary tectonic activities of Babaoshan-Huangzhuang-Gaoliying fault and the regional principal compressional stress direction and regional tectonic activities derived from the recent cross-fault displacement observation data in the Capital area, we have analyzed the relationship between the fault movements at 7 cross-fault observation sites on the Babaoshan-Huangzhuang-Gaoliying fault and the seismicity,conclude that the Capital and adjacent area is soon to enter upon the next active period of earthquakes. The main conclusions are as follows. ① Cross-fault displacement observation can directly reflect the recent activities of the major faults in the region. ② Present fault movement and earthquake activity have a temporal correspondence with each other, they all show alternately quiet and active periods. ③ The intensity of fault movement is a manifestation of the strength of regional principal compressional stress, it also indicates the strength of an earthquake in preparation.
