| Abstract: | Using the broad-band digital data,selected of L≥ 2 .0 waveform data recorded by Shan-dong digital seismic network since 2007 ,we calculated the stress values and moment magni-tude Wfor each earthquake and analyzed the correlation between them.Combinning Shan-dong geological structure and characteristics of seismic activity,wq analyzed stress field dis-tribution and its temporal and spatial variation in Jiaodong Peninsula and the northern wa-ters,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 relation-ship with seismic activity. |
