•Distribution of radon levels are found to be statistically governed by a normal distribution for both pre and post-seismic activities.•In compressive fault lines, radon level tended to increase before the earthquake and decrease towards the time of earthquake occurrence.•For dilation fault lines, no change in radon levels beyond normal variation was observed.
The distribution of radon activity is determined from pre-earthquake data. Analysis using Normal, Gamma, Weibull and Rayleigh distributions indicates that the variation of radon levels in seismically active regions is best described by a normal distribution. It was observed that radon levels would change in compressive fault lines prior to earthquake. Besides that it tended to increase before the earthquake and then decrease towards the time of earthquake occurrences.
