中文摘要DFW-ⅠⅢ型泥石流次声警报器完整地记录了5·12汶川8.0级地震及以后多次>3.0级余震的地震次声波资料。分析表明,此地震次声波为一确定性信号,卓越频率为2~3Hz,其声压随地震震级而变,5·12地震时的声压>40Pa。记录的5·12强震时间较之公布的地震发生时间提前约1min。希望地震次声波能引起相关研究者的兴趣和重视,并进一步探索相关的机理。
英文摘要 The debris flow warning device,DFW-I III Model is used for research and monitor to debris flow originally.It has recorded the data of infrasound waves from Wen Chuan Earthquake,"5·12",2008 of 8.0 degree and all aftershock,which are more than 3.0 degree.The data shows that the infrasound waves are a define signal.It is a simple sine wave.Its predominant frequency is 2-3 Hz.And sound pressure is changed with earthquake degree.For 8.0 degree of "5·12",Wen chuan the sound pressure of infrasound waves is more than 40 Pa(shown by Fig.1 & 2).The time,which recorded for "5·12" earthquake is about 1 min in advance compared with the time announced by National Earthquake Bureau(See table 1).Hereby authors hope this paper will attract researchers’ attention and interesting.And to explore relative mechanism of infrasound wave from earthquake.
