通过对大量地下水异常、动物异常和岩石实验等资料的分析、研究,建立起了一个综合性的临震标志。这一标志的最大特点,不象已有的这类标志是建立在某种单一前兆的某些特征量上,而是建立在由多种前兆现象在时空展布规则性所体现的急速形变场和破裂场的规则变化上。因而可以说,这样一个标志对作好临震预报工作会是大有裨益的。作者将地下水和动物异常分为:无震异常、前兆异常和震后异常三类。指出了各类异常 Through a large number of groundwater anomalies, animal anomalies and rock experiments and other data analysis, research, set up a comprehensive sign of temporary earthquake. The most prominent feature of this symbol, unlike the existing ones, is based on certain characteristic quantities of a single precursor, but on the rapid deformation field represented by the regularity of space-time distribution of various precursor phenomena And rupture of the rules of the field changes. Therefore, it can be said that such a sign can be of great help to the preparation of a temporary earthquake prediction. The authors classify groundwater and animal anomalies into three types: anomalous anomalies, precursory anomalies and post-earthquake anomalies. Pointed out all kinds of anomalies
