Analyst C: Geopsy Processing of MASW and Ambient Vibration Arrays for Vs Assessment of the UTexas1 Surface Wave Dataset

Wathelet, Marc

This paper presents the method and results obtained by analyst C while processing hammer shots recorded along a 94-m line of geophones and passive data collected with three circular arrays (60, 200, and 400 m aperture). Dispersion and ellipticity curves are extracted for Rayleigh waves and provided to the inversion step. The open-source Geopsy software is used for all signal processing. A neighborhood algorithm (NA) implemented in Dinver software is used to invert Vs and Vp profiles. A collection of 3119 profiles is found to fit the dispersion and ellipticity curves taking into account the experimental uncertainties.
