摘要

利用山东数字地震台网的地震波形记录,选取2007年以来台网记录清晰的M_L≥2.0数字地震波形资料,计算每次地震的环境剪应力值τ_0和矩震级M_W,并分析其相关关系;结合山东地区地质构造和地震活动性特点,对胶东半岛及北部海域、南黄海北部地区、沂沭带地区、冀鲁豫交界地区应力场分布和时空变化进行细致分析,并探讨其区域特征及与地震活动性的关系。
Using the broad-band digital data,selected of M_L≥2.0waveform data recorded by Shandong digital seismic network since 2007,we calculated the stress values and moment magnitude Mw for each earthquake and analyzed the correlation between them.Combinning Shandong geological structure and characteristics of seismic activity,wq analyzed stress field distribution and its temporal and spatial variation in Jiaodong Peninsula and the northern waters,the northern region of the South Yellow Sea,Yishu belt regions,Shandong and Henan border region.We also explored the regional characteristics of stress field and the relationship with seismic activity.
