The study shows that the idea of an aerial explosion of a chondritic meteoroid with the
density of 3300 kg/m3, diameter of about 15…20 m, mass of 10…15 kt and explosion en-
ergy of 0,3…0,5 Mt TNT, which took place on Feb 15th, 2013, in the sky to the south-
south-west of Chelyabinsk, is completely out of agreement with the phenomena actually
observed at the moment in the atmosphere and on the underlying terrain. This is proven
by infrasound investigation results, excess shockwave pressure levels in Chelyabinsk and
its surroundings, and data on broken glass, demolished gates and deformed bearing
beams of steel. The mass of the Chelyabinsk meteoroid trail also supports this. The study
analyses available data and explains the reasons why there appeared incorrect yet widely
published estimations of meteoroid parameters and explosion characteristics.
Keywords: Chelyabinsk meteoroid, meteoroid, nuclear blast, infrasound, flash, shock
wave, pressure.
