摘要
本文对预报因子进行了相关性分析,选取了六种非线性预报因子,分别对辽宁地震活动进行研究,它们是:多重分维Dq、时间信息熵Qt、算法复杂性C(n)·空区参数(n)、Hurst指数R/S和深化指数.在此基础上,应用信启、检索的方法,对六种预报因子进行了综合分析.结果认为,在对辽宁地震活动的分析中,采用信息检索的方法,对地震预报的效果有所提高.可作为今后预报工作的重要参考.
Correlation analyses of predictors have been given in this paper.Then, We study seismicity ofLiaoning area by selected six nonlinear predictors-multifractal dimension Dq, time entropy Qt, algorithmiccomplexity C(n), gap parameter (n), Hurst index R/S, and evolution index YH.The curve of every predictor appearsabnormal features before some earthquakes.On the basis of the analysis comprehensive analyzing about sixnonlinear predictors has been performed by method of information retrival. The result shows that the informationretrival brings about a striking effect for earthquake prediction.
