云南水汞群体非均匀度异常与成组强震活动关系

Relationship between Anomaly of Group Inhomogeneous Degree of Mercury Content in Groundwater and Grouped Strong Earthquakes in Yunnan Province

摘要:

阐述了一种前兆群体异常信息提取新方法前兆群体非均匀度的数学原理,并以云南水汞群体异常信息为例进行了具体计算。结果表明该方法以群体异常分布特征的变化为异常标准(ID≥1),达到异常即自动识别报警。该方法能克服个人经验的局限,易为他人进行检验,可成为本地区成组强震预测对应概率较高的新指标。

Abstract:

The mathematics principle of Inhomogeneous Degree（ID） of precursor group anomaly,a new method for extracting precursor group anomaly,is expounded. Taking the group anomaly of mercury content in groundwater in Yunnan province as an example, the method is practical calculated. The result shows that ID of precursor group anomaly can identify and alarm automatically in short-term earthquake prediction with taking the break of distributive features of precursory group anomaly as the anomalous criteria（ID≥1）. The method overcomes personal experiential limitation and can be examined easily by other people. It could provide a new prediction index with high corresponding probability for grouped strong earthquake prediction in Yunnan region.
