摘要

     
    

Precursor anomaly characteristics before strong earthquakes in North China region are studied by the method of quantitatively determining anomalies based on systematic collection and analysis of observation data of underground fluid in this region. The results indicate that medium-term precursor anomalies with uptrend and medium-short-term with transition of underground fluid appeared before earthquakes, and precursor anomaly graphs were comparable before different earthquakes.
