Nonlinear waveform inversion for surface waves with a neighbourhood algorithm: application to multi-mode dispersion measurements

Yoshizawa, K; Kennett, Brian

Description

A new technique for multimode dispersion measurement has been developed by employing fully non-linear waveform inversion for a path-specific 1-D profile using a neighbourhood algorithm (NA). One-dimensional models derived from waveform inversion are quite sensitive to the model parametrization and the reference model used to start the inversion. With different approaches to the parametrization of the shear wave speed profile, we can find models with significant differences in velocity variation...[Show more]
