Propagation of tsunamis over large areas using COMSOL

This paper presents a numerical model based on the mild-slope equation (MSE for short) suitable to reproduce the propagation of small amplitude tsunamis in the off-shore field. The model solves the governing equations in the frequency domain and allows the reproduction of the frequency dispersion for broad banded spectrum sea states. The model application to reproduce laboratory experiments and real life tsunamis in the south Tyrrhenian sea (Mediterranean Sea) are described, showing its applicability to relative large geographical areas. The proposed method is suitable to support a real time tsunami early warning system
