| Abstract: | Based on the digital data of explosion and earthquake recorded by Liaoning Digital Seismological Network, the S wave corner frequency calculation of these records was performed by the means of wavelet analysis. We have compared the result of wavelet research and PITSA program in order to seek for a quantitative index in the recognition of explosion and earthquake. |
