明灯一号及邻近地区地震与爆炸的识别

Identification of earthquakes and explosions in Bright Lamp No.1 and its nearby area

通过明灯一号大当量爆破资料,挑选其周边地区天然地震和人工爆破事件,研究天然地震和人工爆破事件的波形记录特征,并应用两种模式进行识别。结果表明振幅比判据能反映天然地震与人工爆破的本质区别,可以作为识别两类事件的有效判据。两种模式识别方法的U检验效果较好,表明该研究的特征和方法具有实际应用前景。

In this paper, we studied waveform features of Bright Lamp No. 1 large explosion ana the natural and non-natural earthquakes nearby, and identified these events by two kinds of pat- tern recognition methods. The result shows that the amplitude rate criterion can reflect the feature of natural earthquake and explosion and can be used as an effective criterion of distin- guishing these two kinds of events. The U testing result is good enough to show that the features we studied and methods we used in this paper are promising in practical use.
