Wave Characteristics of Blasting Events Recorded by the Chongqing Digital Seismic Network

The paper analyzed wave data of blasting events recorded at Wushan airport by Chongqing seismological network between January and June 2016. The results show that the time-space-strength distributions of blasting events have obvious regularity, and the initial motion of p wave, A_P/A_S amplitude ratio, frequency spectrum etc. of blasting events is obviously different from natural seismic waveform. The results can provide some reference for the judgment of earthquake and explosions signal.
