利用地下水化学预报地震的探讨
PRELIMINARY STUDY ON THE APPLICATION OF HYDRO-GEOCHEMISTRY TO EARTHQUAKE PREDICTION
-
摘要: 我国利用水化学组分变化预报地震已有十年实践历史,通过多次强震的检验,说明地下水化学方法是一种可用的中短期预报手段.本文以华北地区三次大地震为重点,试图通过总结我国近期几次七级以上强地震的水化学前兆反映特征,探讨地下水化学在地震预报过程中的作用及前兆变化的主要影响因素,进而对水化学预报地震的前兆机制进行初步讨论.Abstract: For about a decade, variations in hydrogeochemical constituents have been used for earthquake prediction in China. The experiences in foretelling several earthquakes have indicated that hydrogeochemistry may be an possible means for mid and short-termearthquake predictions. In this paper, by outlining the characteristics of hydrogeochemical anomalies observed before several strong earthquakes with M7 occurred in recent years in China, particularly three of them occurred in North China, an attempt is made to discuss the role of hydrogeochemistry in earthquake prediction and the main factors that influence precursory variations in hydrogeochemistry. Furthermore a preliminary study on the mechanism of the precursory hydrogeochemical anomalies is made.
