The aim of this work is to analyze the possibility of tsunami destruction as a soliton. The rise of the wave packet spectrum of a soliton is possible by multiple and regular mechanical actions (or complex of the actions). The required modulation of the wave packet should be made as an action on an envelope of such impulse (soliton). The soliton mod-ulation can be redundant, that can lead to destruction of the corresponding wave packet. This process leads to the formation of the large amount of combination frequencies, and, accordingly, the spectrum of the resulting wave packet expands. The tsunami modulation can be made by regular (periodical) mechanical actions on the main part of the correspondent soliton or its subsea part. When solitons (such as soliton of nonlinear Schroedinger equation, soliton of Korteweg-de Vries, soliton of sine-Gordon) are regularly, periodically exposed, the initial solitons are destroyed and form the group of ordinary waves, even if with high amplitude. The ordinary waves, formed as a result of actions, are, certainly, dangerous, but such risk is not comparable with the danger caused by tsunami. The solitons can be formed not only in tsunami, but also because of the other natural and man-made disasters. For example, shock waves that appear in the air when large spatial objects are fallen down. Besides this, electromagnetic pulses, appeared as a result of altitude nuclear explosions, and also electric pulses during transient processes in electric and power grids also can be classed as elec-tromagnetic solitons. The destruction of such solitons (the same as other types of soliton) can be made by methods like the method described in this article.
