APPLIED STUDY ON INFORMATION ENTROPY OF WEIBULL DISTRIBUTION IN EARTHQUAKE PREDICTION
Qi Fan · Northwestern Seismological Journal · 2003
On the basis of statistical distribution and information entropy theory,information entropy of magnitude (Hm) and information entropy of interval time (Ht) are defined,and their formulas are derived.By means of specio temporal scanning and calculating,Hm and Ht appear low value anomaly in 1~3 years before strong earthquake.Having the better correlation with earthquakes,the Hm and Ht can be used as earthquake forecast indexes for mid or mid short term.
