在系统整理山东地区水化学观测资料的基础上， 对山东菏泽５９ 级地震、苍山５２级地震及大同６１ 级地震和南黄海５３ 级地震前的地震异常特征进行了分析和总结， 认为水化学多组分的同步异常变化， 反映了震源应力场孕育过程， 多组分的同步异常变化， 具有统一的物理力学机制， 是震前源兆异常的重要标志， 这些异常基本同步出现， 相互印证，增强了异常的可信度， 为短临异常的判定提供了较为充分的依据。某一井孔水化学多组分出现同步异常变化， 预示位于井孔同一活动断裂上未来十几天至几个月有可能发生５ 级以上地震。
Based on systematically analyzing the water chemistry observation data in Shandong Province, the anomalous characteristics of the anomalies before the MS 5.9 Ms Heze earthquake in Shandong, the Ms 5.2 Cangshan MS 6 1 earthquake in Datong and the Ms 5.3 Wen MS in the Yellow Sea After analyzing and summarizing, it is considered that the synchronous anomalous changes of multi-components in water chemistry reflect that the process of source stress field inoculation and the synchronous anomalous changes of multi-components have a unified physical and mechanical mechanism, which are important marks of anomalous precursors before earthquakes. These anomalies Basically appear in synchronization with each other, confirming each other, enhancing the credibility of the anomaly and providing a more adequate basis for the determination of short-term anomalies. The synchronic anomalous changes in the chemical composition of a wellbore water indicate that a magnitude 5 or higher earthquake may occur on the same active fault in the well bore in the next ten to several months.
