| Abstract: | Based on the studies we have done before about the discrimination and criteria between blasts and small earthquakes, we do some researches on the automatic discrimination and criteria obtained from period-spectrum analysis. We also give the criteria of waveform irregular index and predominant period to discriminate blasts automatically, and the discrimination probability reaches 77%. |
| Keywords: | blast automatic discrimination period-spectrum waveform irregular index predominant period |
