摘要
对渤海地区 3级以上地震的扫描分析表明 ,自 1970年以来 ,该区不断出现 3级地震条带或空区等特殊地震活动图像 ,反映了该区应力场的演化过程。同时 ,这些条带或空区图像的出现 ,与外围附近地区的中强地震发生、大区域应力场的调整有关。
The authors have analysed the earthquakes with Ms3 in Bohai area,and found that the special seismicity diagrams of belts or gaps of earthquakes with Ms3 since 1970 reflect the stress field evolution in this area.And the belts or the gaps are related with the mediumstrong earthquakes in the external area and with stress adjustment in large stress field.
