摘要
利用山东省每年地震会商报告给出的地震前兆异常（不是取地震后的震例总结或论文给出的异常），按“专家系统”思想对每一地震前兆异常事件进行综合评估，以每一异常的最可能发震时间来估算发震概率，计算了各类地震前兆异常群体信息熵，研究了苍山ＭＳ５．２ 地震前综合信息熵的变化特征。结果表明：震前熵值减少。
Every seismic anomaly event,choosen from the annual seismic consultion of Shandong Seismological Bureau instead from the postseismic sums up of events or papers,is comprehensively estimated using“earthquake predicting expert system”.And the probability of earthquake occurrence is calculated by means of the most likely earthquake occurring time that corresponds to every anomaly. The comprehensive weighted information entropies for all sorts of seismic precursory anomalies are calculted, and the variation of comprehensive weighted information entropy before the Cangshan M S 5.2 earthquake is analysed. The result shows that before an earthquake the entropy will decrease and the system will turn in order gradually.
