A combined inversion of Rayleigh wave dispersion and 2‐D resonance frequencies [PDF]

, 2017
Shear wave velocities of the sediment fill of a deep Alpine valley are estimated from ambient noise recorded on linear and circular arrays. We propose a combined inversion of 2‐D resonance frequencies identified from site‐to‐reference spectral ratios and
