Application of D-S theory in short-term and impending earthquake prediction of multi-sensor

LI Bin,CHEN Yi(Dept of Computer,Guilin Institute of Electronic Technology,Guilin 541004,China)  
An information fusion algorithm for short-term and impending earthquake prediction by seismic precursor is presented.The algorithm is based on D-S theory and fuzzy mathematics.Firstly,the characteristic values of Geoelectricity,ground stress,groundwater level,short levelling and groundwater radon sensors in the locale are extracted.Then,the concept of membership function in fuzzy mathematics is generalized to D-S theory to produce basic probability assignment(BPA) of earthquake when each precursor occurs.The BPAs fuse according as D-S rule,and through the judge rule of target mode,the situation of earthquake is predicted at last.Through the prediction simulation to 7.8 earthquake of Tangshan in 1976,it is shown that the D-S theory is more efficient and superiority in earthquake prediction.
