Temporal series of the multi precursor observing data has been translated into probability temporal series by using the probabilization processing.Based on the work above,the synthetic information entropy of the information source system which is made up of the multi precursor observing items has been calculated by applying the basic principle of information theory.Calculating the 17 items of precursor observation data in Urumqi and its neighborhood,it has been found that the anomaly process of entropy decrease...

Temporal series of the multi precursor observing data has been translated into probability temporal series by using the probabilization processing.Based on the work above,the synthetic information entropy of the information source system which is made up of the multi precursor observing items has been calculated by applying the basic principle of information theory.Calculating the 17 items of precursor observation data in Urumqi and its neighborhood,it has been found that the anomaly process of entropy decrease appeared half a year to one year before moderate and strong earthquakes.

采用概率化预处理方法,把多种前兆观测值时间序列转化为概率值时间序列.在此基础上,应用信息论基本原理,计算由多种前兆观测项目构成的信源系统的合成信息熵.通过对乌鲁木齐及邻近地区17种前兆观测资料的实际计算,发现在多次中强地震前出现半年至一年的减熵异常过程

Based on probabilistic preprocessing,The observation values for the observed items of subsurface fluid in the joint area of Hebei,Shandong and Henan province have been transformed into probability and time sequence.The synthetic information entropy of the information source system formed by subsurface fluid in the area is calculated.The relation between the variation of the synthetic information entropy and Heze M s5.9 earthquake (1983) and Renxian Ms5.0 earthquake (Hebei province,1985)is analyzed.The results...

Based on probabilistic preprocessing,The observation values for the observed items of subsurface fluid in the joint area of Hebei,Shandong and Henan province have been transformed into probability and time sequence.The synthetic information entropy of the information source system formed by subsurface fluid in the area is calculated.The relation between the variation of the synthetic information entropy and Heze M s5.9 earthquake (1983) and Renxian Ms5.0 earthquake (Hebei province,1985)is analyzed.The results show:there are two times obvious entropy decreasing before the two events and the later is more distinct than the former.The two events both occurred at the low entropy moment.The entropy recovered after the shocks.This process reflects maybe the ordinal change of the entropy decreasing in the course of earthquake development and occurrence for a subsurface fluid information system.Study shows 0.45 is the precursory anomalies' alarm line for an earthquake in the area,and the closer to an earthquake,the larger the entropy decreasing,the greater the magnitude of the earthquake.

采用概率化预处理方法 ,把冀鲁豫交界区地下流体多种观测项目的观测值转化为概率值时间序列 ,在此基础上计算了该区地下流体构成的信息源系统的合成信息熵值 ,分析了合成信息熵值变化与 1 983年菏泽 Ms5.9级地震和 1 985年河北任县 Ms5.0级地震的关系 ,结果显示 ,在这两次中强地震前分别有两次明显的减熵异常过程 ,并且一次比一次减熵过程更明显 ,中强地震都发生在低熵值处 ,震后恢复到高熵值。这可能反映了地下流体构成的信息源系统在地震孕育和发生过程中的减熵有序变化。通过研究认为该区减熵到 0 .45为发震前兆异常警戒线 ,并且离中强地震发生的时间越近 ,减熵过程越大 ;震级越大 ,减熵过程越明显
