The overpressure and wind speed behind the shock wave front, leading to various dangerous effects, can be estimated on the basis of specially developed models of the interaction of cosmic objects with the atmosphere and the Earth\u2019s surface. The shock wave is also the cause of seismic effects, but this work only considers the direct effect of the shock wave. A serial numerical modeling of the interaction of cosmic objects with the atmosphere has previously been performed for a large number of different scenarios under the hydrodynamic model. Analysis of the modeling results provides scaling relations that allow you to estimate the overpressure, wind speed behind the shock wave and their distribution on the surface, if you know the impactor\u2019s parameters, its velocity and trajectory inclination angle. These relations take into account the spatial inhomogeneity of the overpressure distribution on the Earth\u2019s surface. The suggested scaling relations were tested on the data of the Chelyabinsk and Tunguska events, which showed a good correspondence with the observed destruction data. The obtained scaling relations are used in the online calculator (http:\/\/www.AsteroidHazard.pro), which allows you to quickly and quite accurately estimate the various effects of impacts.”<\/p>\n","protected":false},"excerpt":{"rendered":"
