摘要
利用“地震预报计算机专家系统”的思想对大同 -阳高 Ms6 .1地震前每一前兆异常事件进行综合评估 ,以每一异常的最可能发震时间来计算发震概率 ,利用地震前兆综合加权信息熵研究了系统熵值与地震的关系。对华北地区的地震前兆综合加权信息熵研究表明 ,在大同 -阳高 Ms6 .1地震前 ,信息熵出现了明显的减熵有序变化
In this paper,each anomaly event before Datong-Yanggao earthquake(\%M\%s6.1) is comprehensively estimated by using "Earthquake Prediction Exprert System". Probability of anomaly appearance is calculated by means of the most likely time of earthquake occurrence for each anomaly.Using comprehensive weighted information entropy of seismic precursors the relation between the information entropy of the system and earthquakes is investigated.The analysis of comprehensive weighted information entropy of seismic precursors in North China shows that system entropy decreased in regular order before the Datong-Yanggao earthquake.
