Cometary impacts on Earth, as comets themselves, especially aperiodic ones, have been much less studied compared to asteroids. Nevertheless, despite the rarity of such impacts, they occurred in the past and cannot be ruled out in the near future. Mor

—Destruction on the Earth’s surface caused by a shock wave is one of the most important and dangerous effects from asteroid and comet impacts. The overpressure and wind speed behind the shock wave front, leading to various dangerous effects, can

—Mass industrial explosions on extended benches of open pits are the most effective way to crush rock. Such explosions are accompanied by the rise of a gas and dust cloud. Three-dimensional numerical experiments are used to study the interaction of

The results of numerical simulation of kilometer-sized asteroid impacts on different types of terrain (a flat surface, a mountain, and a depression) are presented. The results show that terrain features significantly affect the amplitude of the shock

In this paper we present the results of numerical modeling of the Chelyabinsk dust train during the first 3 min after the meteoroid entry which are in qualitative agreement with observations. Then we analyze the possibility of plume formation after i

The numerical analysis of the propagation of shock waves initiated by either a space body striking the Earth’s surface, or underground explosions, allows us to compare the energies required to attain the same amplitudes of shock waves at impacts an

Numerical simulation of the destruction, evaporation, deceleration, and emission of the Chelyabinsk superbolide has been carried out. The model assumes that the main energy is radiated in the stage when the asteroid is already completely destroyed an

The extraordinary Chelyabinsk airburst of 15 February 2013 is considered in the frame of quasi-liquid model (QL model), in which the entering body is treated as a strengthless quasi-liquid object, and its deformation and the flow are described by the

We present the results of numerical simulation for impacts of relatively small asteroids and ice bodies of 30–100 m in size, decelerated in the atmosphere and exploding before they reach the surface, but still producing seismic effects due to the i
