| 摘 要： | 本文通过对山东半岛及附近海域地质构造分析、地震学参数时空扫描计算、地震背景形势分析等认为：山东半岛及附近海域有发生5级左右地震的异常背景。预测区域为：胶东及北部海域3-4级地震条带及边缘有发生4.5级左右地震的可能；渤海海域自1969年7.4级地震后，其地震能量释放呈下降趋势，近20年活动水平为4级左右，渤海海域近期发生大于5级以上地震的可能性较小。北黄海海域近几年地震活动水平明显高于渤海海域。北黄海未来一、二年或稍长时间有发生5级左右地震的可能，应注意山东半岛及北部海域地震活动趋势的发展。

| Abstract: | By analyzing the geologic structure,scanning time,space of parameters,and the situation of earthquake background of Shandong Peninsula and the waters nearby Shandong Peninsula,it may be concluded Shandong Peninsula and the nearby waters have the abnormal background under which would earthquake take place around 5 magnitude.It has been forecasted that Jiaodong and the sea area of the northern(the earthquake belt of 3-4 magnitude) about 4.5 magnitude earthquake will be likely to take place.The seismic energy ... |
