| Abstract: | In this paper, the data is selected by the explosion and seismic waveform recorded by Ulanhot Seismic Station. Using wavelet analysis way, 3 waveform characteristics of explosion and seismic waveform are extracted. Finally, the effect test of classification is performed using v-SVC support vector classification method. The results show that WPT(db4) + Shannon entropy characteristic + v-SVC is the best combination to differentiate the explosion from seismic events recorded at Ulanhot Seismic Station, which can be used for the rapid identification of explosion and earthquake at Wulanhot Seismic Station. |
