摘要
通过计算营海岫地区1999年以来发生的4次比较显著震群的应力降,探讨了应力降随时间和空间演化的特征,为营海岫地区地震序列的判定提供了参考。
Based on calculating the stress drop of the four sequences which have been occurred in Yingkou,Haicheng and Xiuyan since 1999,the time and space characteristics are discussed in this paper.The method of stress drop could be referenced in the judgment of the earthquake sequences occurred in Xiuyan,Haicheng and Yingkou regions.
