| Abstract: | Noticing that the wavelet analysis possesses a characteristic of high resolution in time and frequency domain,this paper develops a method of extracting wavelet medium-term anomaly from water radon and water level observation.The extraction process includes,through research,deciding the objective earthquake expected to be predicted,selecting testing items and observation wells,extracting wavelet anomaly,identifying the property of the precursor anomaly,etc.(seven steps).With the methodology of extraction of... |
