Abstract

Shear wave velocity models can be built through surface wave analysis. For the presented field case, preliminary data analysis has evidenced the possibility of retrieving several modes of vibration of Rayleigh waves and this suggest the use of a multimodal inversion algorithm to estimate a pseudo-3D shear wave velocity model. The full analysis has been performed starting from a preliminary Monte Carlo inversion applied on the representative dispersion curves. After the Monte Carlo inversion, which provides a consistent 1D reference model for each line, the dispersion curves have been inverted simultaneously adopting a linearised laterally constrained inversion (LCI) to obtain a pseudo-3D shear wave velocity model.
