It is established, on the basis of an analysis of refined distribution of previously published factual parameters of ejecta craters for 14 nuclear explosions (air, near-surface, and underground), that there exists a single relation which characterizes the parameters of the crater formed by the nuclear charge, irrespective of the placement conditions of the charge. It is shown that even though the mechanism of crater formation is observed to be the same, the energies expended in the nuclear charge on fracturing and ejecting rock is approximately 10 times less than for chemical explosives. 4 figures, 2 tables, and 17 references.
