| 摘 要： | 分析了鲁东-黄海活动地块构造背景和历史地震活动特征，探讨了该地块强震前中期阶段地震活动的演化图像，得到该区域强震前中等地震密度增长率能够较好反映强震前中期阶段的异常特征。根据该区域近百年来地震活动基本格局的演化总貌，结合当前应变积累水平，加深了对这一地区今后地震趋势的认识。

| Abstract: | We have analyzed the tectonic background and history seismicity in Ludong-Huanghai active block and discussed seismic evolution images of med-term stage before strong earthquakes.The results indicate that the density increase rate of moderate earthquakes can reflect abnormal feature of mid-term stage before strong earthquakes.According to evolution characteristics of earthquake activity in this area in recent hundred years and the level of seismic strain accumulation at present,it will be helpful for us to study deeply the future earthquake activity tendency in this area. |
