Abstract

This article explored the possibility of spread of weak seismic signals and low attenuation. The results showed that both underground seismic signal propagation medium showed a degree of elasticity,the vibration signal amplitude,just below the elastic limit attenuation is very small,showing low attenuation characteristics. This feature ensures that on the ground,and even the loess coverage area of micro seismic signal detected.
