| Abstract: | In this paper, the basic principles and methods of determining seismic source characteristics and of analyzing seismic source cepstrum are described from the aspects of mathematics, geometry and physical dimensions. The method has been applied to the small earthquake and explosion analysis. The results showed that the cepstrum of 6 times small earthquake at Ko- rea Peninsula have significant difference to that of explosion in the peak. The quantitative parameters C of the cepstrum is great than 1 when it is an earthquake or less than 1 when it is explosion. |
