There exists extraordinarily affluent literature of historical earthquake.Currently,we inadequately utilize macro phenomena of earthquake and isoseismal,therefore,further explore the source of historical earthquake,and emphasize the uncertainty of epicenter and magnitude of historical earthquake.Since 1970,along with the advancement of observational technique, we greatly improve seismic observational accuracy,and moderate and small seismic data recorded by instrument is more and more sufficient.

According to the variance module and resolution after deconvolution, the ideal mixed phase wavelets may be extracted from the wavelet gatherings with the same amplitude spectrum and different phase spectrums finally. Therefore the target for raising the resolution of seismic records can be attained by the determinacy wavelet deconvolution. Through the wavelet extraction tests for theoretic synthetic records and actual seismic data and the processing of enhancing resolution of seismic data by use of the wavelets extracted, it was shown that such a method is correct and effective.

The issues of present seismic wavelet frequency caused by different concepts, such as apparent frequency, dominant frequency, peak frequency and centroid frequency, etc., which are defined by different methods, and understanding deviation, definition of seismic wavelet frequency for time and frequency domain are concluded and summarized. On this basis, three kinds of seismic wavelets in common use such as Ricker and Zinc wavelets as well as sine wavelet with exponential attenuation characteristics are analyzed and a conclude is achieved that apparent frequency and dominant frequency are consistent in essence, but peak frequency and centroid frequency as well as apparent frequency or dominant frequency are not completely consistent with different seismic wavelets. For actual seismic data, peak frequency can approximately be used as dominant frequency, but it is not suitable when seismic wavelet is known for it can give out any wrong knowledge and results.
