In this paper,each anomaly event before Datong-Yanggao earthquake(\%M\%s6.1) is comprehensively estimated by using "Earthquake Prediction Exprert System". Probability of anomaly appearance is calculated by means of the most likely time of earthquake occurrence for each anomaly.Using comprehensive weighted information entropy of seismic precursors the relation between the information entropy of the system and earthquakes is investigated.The analysis of comprehensive weighted information entropy of seismic precursors in North China shows that system entropy decreased in regular order before the Datong-Yanggao earthquake.
