摘要
本文利用森下播散指数研究东北地震,选取5个区域进行Iδ计算,结果表明:森下指数出现高值异常与所研究区域的中强地震对应关系较好,有的地震在高值异常时发生,有的在其后0.5a~2a发生,反映了不同的地震活动类型,应用该方法可以对东北地区中强地震进行一定程度的中短期预报。
In this paper,the Morishita spread index has been applied to earthquake prediction research in NE china. Iδ results obtained from 5 selected area show that the high value anomaly of Morishita index is possessed close relationship with strong earthquake happened in the study area.Some earthquake occurs when high value anomaly shows.Someone occurs in 05~2 years after high value.It indicates different seismicity.Application of the method has advanced in mediumshort term prediction in NE china area.
