COMPARISON OF SEISMOTECTONICS AND SEISMICITIES BETWEEN THE XIALIAOHE LAIZHOUWAN SEGMENT AND THE WEIFANG-JIASHAN SEGMENT OF THE TANCHENG-LUJIANG FAULT ZONE

摘要: 从地震构造和地震活动角度,对郯庐断裂带下辽河-莱州湾段和潍坊-嘉山段进行了对比,认为这两段的地震构造环境具有明显不同,地震活动明显属于不同模式。其中下辽河-莱州湾段属群集型地震活动类型;潍坊-嘉山段属特征型地震活动类型。对于下辽河-莱州湾段,未来应注意在新的活跃期或活跃幕到来时群集型强震、中强震的连续发生;对于潍坊-嘉山段,则应注意断层分段本身所控制的地震复发重现规律。Abstract: The comparison of seismotectonics and seismicities between the Xialiaohe-Laizhouwan segment and the Weifang-Jiashan segment of the Tanlu fault zone has been made.The results show that their seismotectonic conditions are different and their seismicities belong to different models.i.e.the seismicities of the Xialiaohe-Laizhouwan segment belong to clustering type while that of the Weifang-Jiashan segment characteristic type.On the Xialiaohe-Laizhouwan segment,attention should be paid to the successive occurrence of strong and medium earthquakes of clustering type in future active period or episode while on the Weifang-Jiashan segment,the reccurrence of strong earthquakes controlled by fault segmentation should be cared.
