this happens about once every 100 years in 1908 , the tunguska meteorite fell.mple, the tunguska sore collapsed gradually under the influence of aerodynamic loads of the body begins to deform, flatten, then collapses into small fragments that evaporate, but the shock wave. tumbled down the forest at a distance of 60 km. it caused an earthquake, and the radiation approached somewhat , while not a single fragment, most likely , reached the ground. everything happened at an altitude of about 30 km. the chelyabinsk meteorite collapsed at about the same distance, but its remains fell into the lake, chebarkul. why , most likely, the angle of entry into the atmosphere was different. the tunguska flew longer and the chelyabinsk meteorite evaporated for complete destruction there was not enough time. we are also lucky that it happened. it is known that during the fall of the chelyabinsk meteorite, the amount of meteorites, by mass, constituting less than one percent of the isc. the mass does not pull the remnants of meteorites of great value to scientists, because this i
