Multi-channel analysis of surface waves using Common Midpoint Cross Correlation method



Having knowledge about elastic prosperities of different layers of Earth has many useful applications in geophysical and geotechnical engineering projects. One of the important parameters in determination of static constants and the key parameter controlling the amplification of seismic motion during earthquake is shear-wave velocity. Because of the dispersive characteristic of Rayleigh waves when traveling through a layered medium and the important role of S-wave velocity in determination of Rayleigh wave velocity, dispersion of phase velocity of surface waves can be used for near-surface S-wave delineation. In this study Common Mid Point Cross-Correlation analysis of multi-channel surface-wave data (CMPCC MASW method) is used for dispersion curve determination of 2-D seismic reflection survey data.
