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

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.
