摘要
经历史震例及近几年地震震前短临跟踪预报实践 ,对宏观异常进行深入剖析 ,认为 :宏观异常内容和数量多少与震级有关 ;宏观异常不只是短临和临震异常信息 ,也有不少是中短期、短期异常信息 ;宏观异常分布在震中及附近地区 ;最早出现的宏观异常地点对未来地震震中有一定指示意义。
After experiencing historical earthquake cases and short-term and impending earthquake tracking and prediction practices,a thorough research on the macroscopic anomaly is made and a cognition is got that the item and number of macroscopic anomaly are somewhat related to magnitude of earthquake.The macroscopic anomaly is not only of short-term and impending information,but also of moderate-term ones.The macroscopic anomaly are normally distributed around the epicenter and the adjacent,and that the location where macroscopic anomaly appears first indicates the future epicenter of an earthquake.
