摘要
本文将一定震源区域内的地震前兆观测视为一个相对独立的信源系统,利用信息熵方法定量研究地震孕育前兆的复杂性。计算结果表明,在若干次地震前,出现前兆系统的减熵异常过程,显示出在地震的孕育过程中,震源系统从无序向有序演化的过程。
In this paper,the seismic precurser observations in a given source region are to be taken as an information source system of relative independence to quantitavely carry out the research into the complexity of seismogenic forcursor through the entropy of information. The results show that the anomalous process on systematic decreasing entropy appears prior to several earthquakes, which indicates that the source system has evolved from disorder to order transition during the period of potential for earthquakes.
