Infrasonic Signal

The methods of observing and processing infrasonic signals from earthquake sources are discussed in this paper. The categories of earthquake infrasound are firstly discussed. Spectrum analysis as well as travel speed calculation are used to distinguish high frequency local infrasound from the acoustic-gravity wave. Monitoring network has been established to capture the signals from the atmosphere. Basing on a simplified correlation method, a triangle array made of three sensors can decide the direction of the coming signal, and locate the earthquake sources. The calculation error and steps of further improvement are also discussed at the end of the paper.
