Abstract

Passive seismic interferometry (SI) is an increasingly popular seismic method due to its cost-efficient advantage because it does not need an active source. Techniques in using SI to retrieve surface waves are relatively well established, but using SI to retrieve body waves is still under development by many authors. These geophysicists have proved that many factors, such as average duration of the natural sources, the number of natural sources that occurred during recording time, source distribution, etc., influence the quality of body waves retrieved. In this research, I focus on how to make use of the attenuation property of weathered layers to weaken the negative impact of surface noise. First, I model the negative effects of surface noise. Then, I test the effect of burying the receivers in order to improve the retrieved body waves. Finally, I discuss some solutions for removing multiples reflected from free surface.
