Abstract
Summary
We present the results of analysis of two full-waveform inversion formulations using surface waves. We explicitly construct the approximate Hessian matrix and study its properties using a truncated SVD approach. This analysis allows us to understand characteristics of the inversion algorithm such as the expected shape of the recovered solution, uncertainty of the results and the expected properties of local minimization algorithms being applied to this problem. This information should be useful for further development of the inversion strategy and for interpretation of the inversion results.
