RESEARCH ON THE FEATURES AND THE HYDROGEO-CHEMISTRY CIRCUMSTANCES OF FOCAL REGIONS OF THE MODERATELY STRONG EARTHQUAKES IN TIANJIN AND ITS VICINITY
-
摘要: 天津及邻近地区自 1966 年 3 月6 日至今卅余年的时间内先后发生了邢台、渤海、唐山三次 7 级以上大地震和十余次 6 级中强地震,为研究该区的水文地球化学环境提供了有利条件,作者依据该区域内 392 口井,5000 多个水样,20 余个项目的分析资料,探讨了中强地震震源区水文地球化学环境与特征,为探索利用水文地球化学方法判定潜在震源区开辟了新的途径。Abstract: Three earthquakes of magnitudes over 7 and more than 10 earthquakes of magnitudes over 6 occurred in Tianjin and its vicinity since the 1966 Xingtai earthquake,it provides favorable conditions for studying the circumstance of hydrogeo-chemistry.The authors have approached the features and the hydrogeo-chemistry circumstances of the moderately strong earthquakes on the basis of the data of 392 wells and over 5000 water sampoles,our research explores a new way to determine the potential seismic region by using the method of hydrogeo-chemistry.
