地震前兆综合加权信息量是在地震综合信息量的基础上 ,改进了地震前兆异常出现概率的计算方法后 ,得出的一种综合预报新方法。利用“地震预报专家系统”的思想对每一异常事件进行综合评估。考虑到异常的可靠性、有效性、显著性及相互关联性给予不同的权重 ,以每一异常事件的最可能发震时间来估算异常出现的概率 ,计算了华北地区19 84年以来地震前兆综合加权信息量 ,分析了 1998年 10月 19日大同 -阳高 Ms6 .1级地震前这种信息量变化的特点。
The synthetic weighted information of earthquake precursors is a new method of comprehensive forecast obtained after the method of calculating the probability of occurrence of earthquake precursory anomalies based on the amount of earthquake comprehensive information. Use the idea of “earthquake prediction expert system” to make a comprehensive assessment of each anomalous event. Taking into account the abnormality of reliability, validity, significance and interdependencies given different weights, the most likely occurrence of each anomalous event to estimate the probability of occurrence of anomalies, calculated in North China since 1984 the earthquake precursor synthesis Weights of information, the analysis of the October 19, 1998 Datong - Yanggao MS6. 1 before the magnitude of this information changes in the characteristics.
