Abstract—

The results of numerical modeling of the vertical fall of ten-kilometer asteroids onto a solid surface and into an ocean with a depth of 1 to 7 km are presented. The calculations obtained the maximum masses of water and soil emitted into the atmosphere, as well as the masses of water and soil remaining in the atmosphere 30 minutes after the impact. It is concluded that that when asteroids about ten kilometers in size fall into the ocean, the impact on the Earth’s atmosphere will, apparently, be no less strong than when asteroids fall on land.
