Kinetic energies against masses for meteoroids producing LIFs observed by NELIOTA for various η values. Representative energies are also indicated for estimating the damage that a meteoroid impact may cause. We note that the muzzle energies of typical weapons (e.g., pistols and rifles) or stronger military weapons (e.g., machine guns) are less than 3–5 kJ, i.e., two orders of magnitude lower than the minimum energy that the plot covers.
