Abstract：This paper presented a discriminant algorithm based on the similarity of wave envelopes to discriminate seismic events in the same site.The events in a fixed site were analyzed to evaluate the discriminating performance for under-ground explosions.The result shows good performance.When the false alarm rate is about 6.3%,the misclassification rate for explosions with inter-distance smaller than 15 km is only 0.5%,and that for explosions with inter-distance of 15—30 km is about 5.0%.Comparison with the result from the algorithm based on waveform cross-correlation indicates that the method in this paper can discriminate explosions with much larger inter-distance.
