- 摘要:
-
阐述大地震前低频地声的波形和频谱的特征.论述了震前低频地声的形成及声波传播规律,指出震前低频地声具有近场穿透能力、信息可靠及易于提取和接收等优点,是探索近场地震短期前兆信息的重要手段.频谱分析结果表明,震前低频地声异常的频谱大多集中在0~200Hz的低频段,观察表明,近场地震发生前低频地声异常信息强烈.

An exposition is given to the low frequency characteristic of earth sound as a seismic precursor,chiefly the characteristic of waveform and frequency spectrum.As indicated by observed results,prior to the occurrence of near field earthquake,low frequency
