The work carried out the influence of the Chelyabinsk meteorite's bow shock wave on the earth surface. 3D formulation for gas dynamic and seismic part is used. Governing equations of gas dynamic models are the Euler equations with radiation term and the equations of linear elasticity for seismic part are used. Two parts of the model are matched by the direct mechanism of the disturbance transmission. A comparison of the model signal with the real seismic signal data is carried out. Modeling allows refining the characteristic parameter estimation phenomenon (the height of the explosion, the density and the characteristic dimensions of the meteorite).
Keywords: Chelyabinsk meteorite, mathematical modeling, linear elasticity equation, bow shock wave, seismic waves, surface waves, Rayleigh waves.
Mots-clés : Euler equations
