Preseismic radon (Rn-222) emanation is considered to be one of the main physical mechanisms of electromagnetic precursory phenomena. In this paper, we analyze the atmospheric radon concentration around the occurrence time of the 1995 Kobe earthquake, and evaluate the influence on the atmospheric ele...
