The existence of specific pre-seismic variations in parameters of natural geomagnetic field variations in the frequency range from fractions of Hz to several Hz have been reported in numerous studies. However, the problems of statistical validity these effects, their relation to parameters of forthcomins earthquakes and possible physical mechanisms are not solved till now. In the present study we verify the hypothesis about spatial re-distribution of local and regional thunderstorms as a possible source of these variations and discuss its possible relation to radon emanation by an active fault.
