TIP中期地震预报方法CN算法在河南省及邻区的检验与应用
|
摘要
应用ＴＩＰ中期地震预报方法中的ＣＮ算法，对河南省及其邻区发生的中等地震进行了回溯性检验。结果表明内符效果较好，被检验的中等地震中有８０％震前出现了ＴＩＰ，ＴＩＰ警戒时段占总研究时间的２３．３％，综合计算报准率Ｒ值为０．５９。说明该算法对中等地震的中期预报具有实用意义。
After using the CN algorithm which is a way of up medium-term earthquake predictions to have a recalling test on the moderate earthquakes occurred in Henan province and its neighboring area, the result calculated shows that the correlativity is good, there are 80% of earthquakes tested to have the symptom of up before the earthquake, TIP precaution period only takes up 23. 3% of the whole research time and the value of comprehensive calculahon accuracy rate is 0. 59. Thus the algurithm is shown to ha a prachcal predichon for predicting moderate earthquake in medium-term.
