摘要
多年来利用地下流体异常预报地震主要依靠的是单项观测资料(诸如地下水位或水氡含量等),随着地震预报研究的深入和监测技术的发展,开展单井多项观测和提取综合前兆异常已是面临着的新任务.本文据张道口井的多年多项流体观测资料,提出了单井流体异常综合信息量的计算方法.结果表明,在唐山7.8级和大同6.1级地震前该信息量均有明显的异常显示.
Based on the study of anomalies of μ-value of many observations of fluid in Zhangdaokou well and its comprehensive information value with dynamic subfunction, it is found that the anomalies of comprehensive information occurred before 1976 Tangshan (M = 7. 8) and 1989 Datong (M = 6. 1) earthquakes.
