| Summary: | The results of the numerical simulation of possible hydrodynamic
perturbations in Lake Chebarkul (Russia) as a consequence of the meteorite
fall of 2013 (15 February) are presented. The numerical modeling is based on the
Navier–Stokes equations for a two-phase fluid. The results of the simulation
of a meteorite entering the water at an angle of 20° are given.
Numerical experiments are carried out both when the lake is covered with ice
and when it is not. The estimation of size of the destructed ice cover is
made. It is shown that the size of the observed ice hole at the place of the
meteorite fall is in good agreement with the theoretical predictions, as well
as with other estimates. The heights of tsunami waves generated by a small
meteorite entering the lake are small enough (a few centimeters) according to
the estimations. However, the danger of a tsunami of meteorite or asteroid
origin should not be underestimated. |
