河北唐山地区发生了7.8级地震(1976·7.28)后,由中国科学院生物物理研究所、动物研究所、河北省地震局等单位组成联合考察组,对唐山地震前的动物异常现象进行调查研究,共搜集到三十余种动物的震前异常2093起,其中大牲畜、鸡、鼠、猪、狗、羊、鱼、鼬等动物的反应较为普遍,占总异常量的80%左右.唐山地震前为什么这些动物会发生异常现象?探讨这个问题将有助于利用动物异常作临震预报.
After the 7.8 magnitude earthquake (1976 · 7.28) occurred in the Tangshan area of Hebei Province, a joint investigation team composed of the Institute of Biophysics, Chinese Academy of Sciences, the Institute of Zoology and the Seismological Bureau of Hebei Province conducted an investigation on the anomalous phenomena of animals before the Tangshan earthquake. A total of 2093 anomalies of more than 30 species of animals were collected before the earthquake, of which the reactions of large animals, chickens, rats, pigs, dogs, sheep, fish and weasels were relatively common, accounting for about 80% of the total anomalies. Why do these animals have anomalies before? Exploring this issue will help to make use of animal anomalies for earthquake prediction.
