地下流体中期和中短期前兆异常的四种判定方法

Abstract

Abstract: Basedon earthquake precursory anomaly characteristics of ground fluid, and according to the “identity ” technical thinking of analysis and Prediction method, four methods, suchas difference, subordinate function, variational difference and change rate, are screened out from current analysis and prediction methods. This paper introduced calculation form ula and methods for those four kinds of anomaly-judging method. Combining the earthquake case data, these methods are examined and the effect is good.

Key words: Ground fluid, Medium-termanomaly, Judge method
