动物的行为异常是一种临震前兆

本文论述了地震前动物行为异常出现时间的分布特点及其与孕震过程和其他地震前兆的某些短临异常之间的关系.这些分析结果如下:1.地震后所搜集到的一般性资料的分析表明, 大多数的动物行为异常出现在震前一天内.2.201例动物行为异常出现时间的分析表明, 大多数的行为异常出现在震前11小时内, 并在震前2—3小时急剧地增加.异常的平均出现时间和标准偏差分别为2.7小时和2.5小时.由此可见, 动物的行为异常确是一种在临震前出现的宏观前兆现象.3.对异常时间与地区分布特点的分析表明, 大多数的动物行为异常出现在孕震过程的临震突变阶段, 并与该阶段中急剧出现的其他地震前兆的临震异常有关.

ANIMAL ABNORMAL BEHAVIOR IS AN EARTHQUAKE SHORT-TERM PRECURSOR

This paper deals with the characteristic of the distribution of appearing time of unusual animal behavior prior to earthquakes and its relations to some other presumably short-term earthquake precursors and to the different development stages of the earthquakes. The results of analysis are as follows:1. The analysis of data collected after many earthquakes shows that most of the anomalous animal behaviors occur within one day before the earthquakes.2. The analysis of 201 cases of abnormal animal behavior shows that most of them occur within 11 hours and increase sharply 2—3 hours before the earthquake. The mean appearing time of the anomaly and standard deviation respectively equal to 2.7 and 2.5 hours. So we suppose that the unusual behavior of animals is possibly a short-term macroscopic premonitory phenomenon of the earthquakes.3. The analysis of the characteristic of time-space distribution show that most of the unusual animal behavior appear within the breaking stage of the process of development of the earthquakes and associate with some short-term anomalies of other phenomena occurring suddenly within this stage.
