通过对1970年以来胶东半岛及其北部海域ML3．5级、环渤海区域ML4级、华北地区ML5级以上地震时序及活跃时段分析，认为三区域地震活动具有相关性，胶东半岛及其北部海域地震是环渤海、华北地区地震活动的震情窗口，同时地震空区、条带、胶东半岛及近海震群和地震小序列活动，为环渤海区域中强震前中短期判定指标。

According to the analysis of the seismic sequence and active period of more than ML3.5 earthquakes in Jiaodong Peninsula and the northern waters , more than ML4 earthquakes around the Bohai Sea region and more than ML5 earthquakes in North China since 1970, it is concluded that the three regional earthquake activities has correlation. Earthquakes in Jiaodong Peninsula and the northern waters are the indicative window of earthquake activities around Bohai Sea and North China. While seismic gap , bands, earthquake swarm and small earthquake sequence activity in Jiaodong Peninsula and Offshore could become the short-term determination index before strong earthquakes in Bohai region.
