摘要
从形变异常机理出发,对大震前出现的几种异常的关联性进行分析,同时结合观测事实和实验进行验证,探索其间可能存在的有机联系。对大震前的大旱、大震后的暴雨、大震时的喷沙冒水和地面塌陷、地声和地光以及大震前的电离层异常、大气静电异常、震前及震时电磁波异常等现象从机理上给出统一解释,认为这些异常现象均与大震前震源体附近微裂膨胀体的形成、扩展有关,并随着大震发生而迅速消失。
Based on the mechanism of deformation anomaly,we analyze the correlation of several anomalies before the earthquake.Combined with observation facts and experiments,we explore the possible organic connections between them.The explanations are given uniformly from the mechanism for the anomalies before and after the earthquake,such as the severe drought before the earthquake,the heavy rain after the earthquake,the sand jetting and ground collapse during the earthquake,as well as ground sound and light,the ionosphere anomaly before the earthquake,the atmospheric electrostatic anomaly before the earthquake,and the electromagnetic wave anomaly before and during the earthquake.We consider that these anomalies are all related to the formation,expansion and rapid disappearance of micro-crack expansion bodies near the seismic source before the earthquake.
