THE STUDY OF INFORMATION MAGNITUDE OF EARTHQUAKEPRECURSORS (Ⅲ) THE APPLICATION OF INFORMATION MAGNITUDE METHOD OF EARTHQUAKE PRECURSORS IN THE STUDY OF DATONG EARTHQUAKE

    摘要
  • 摘要: 本文采取统一分析模式,系统地研究了1989 年大同5.8 级地震前河北省及其邻近地区各种前兆观测手段所出现的异常变化,并计算了这些异常所提供的前兆信息量,在此基础上,得到了大同地震之前前兆信息场的时、空动态图像,发现1989 年大同5.8 级地震前,河北省及其邻近地区前兆信息场,先在震源附近及外围出现,尔后向震源区边缘迁移集中,在保持震源区边缘较强信息的同时,前兆信息又向外围扩展,不久即发生地震。

     

    Abstract: In this paper,based on the method of calculating earthquake anomalous precursory information magnitude given by document1,the anomalous variations of presentation of various precursory observation means in Hebei province and its vicinity before 1989 Datong Ms 5.8 earthquake were analysed in a systematic way and precursory information magnitude provided by these anomalies was calculated.On the basis of this,the dynamic images of precursory information field in time and space before Datong earthquake were got up and its evolution active characteristics were studied.
