Surface-wave mode coupling : modelling and inverting waveforms including body-wave phases

Abstract

This thesis is concerned with a similar problem as addressed by Li & Tanimoto (1993) in the surfacewave mode approach. In this thesis it is shown that surface-wave mode coupling is required when body-wave phases in laterally heterogeneous media are modelled by surface-wave mode summation. An efficient inversion method that includes surface-wave mode coupling is derived and applied to a large-scale regional inversion for S-wave velocity structures beneath Europe, the north-eastern Atlantic and western Asia.
