Numerical simulation of a tsunami source: the case study of the Peru coastal area

This paper studies the importance of spatial distribution of the sea-level monitoring stations for the accuracy of restoration of a tsunami source. The ill-posed inverse restoration problem is regularized by means of the least squares inversion using a truncated SVD approach. The wave propagation is described by linearized shallow-water equations when depth depends on an arbitrary function of two variables. Results of numerical experiments are presented in the case study of the Peru coastal area.
