Pre-seismic variations of atmospheric radon activity as a possible reason for abnormal atmospheric effects

Abstract: Possible atmospheric effects associated with pre-seismic variations of atmospheric radon concentration occasionally observed prior to earthquake occurrence are subjected to theoretical study in order to assess their potential effectiveness. Altitude distribution of atmospheric conductivity is examined as a function of radon and aerosol concentrations. Horizontal components of atmospheric electric fields and currents, which can arise near a boundary of seismo-active region, are estimated. We speculated that cha… Show more

“…These particles generate a large number of ion pairs in the air through radioactive ionizing radiation, leading to the formation of a polarization electric field that opposes fair weather conditions. Considering the exclusion of meteorological variations and other factors that may influence the negative anomaly of the AEF, it is plausible to attribute the negative anomaly of the AEF in seismogenic areas to abnormal signals arising from the extensive micro-fracturing of rocks induced by large-scale geological tectonic activities [55][56][57].…”

“…This resistance is changed as a result of the injection of radioactive, chemically active substances, aerosols into the atmosphere and variation in the atmosphere conditions. It has been shown that radon emissions into the atmosphere can change its conductivity by tens of percent [Omori et al, 2008;Harrison et al, 2010;Surkov, 2015], while they do not affect the electric field in the ionosphere. Calculations of the electric field penetration into the ionosphere, performed in [Kim and Hegai, 1999;Pulinets et al, 2000;Pulinets, 2009;Denisenko et al, 2008] showed that its value is orders of magnitude smaller than the background value in the ionosphere.…”

“…On the other side Pulinets and Ouzounov 2011 pointed out that the discrepancy between the claim that radon exhalations are a precursor to earthquakes (Toutain and Baubron, 1999;Omori et al, 2007;Pulinets, 2007) and the demonstration that radon releases are not a statistically reliable precursor (Geller, 1997) cannot be easily resolved with local measurement stations, due to the variety of measurement methods adopted worldwide and the uncertainty about the origin (crustal or mantle) of radon and the related transport models. Due to the difficulty of monitoring radon on the ground-with networks with high spatial resolution (İnan et al, 2008) over large areas (such as within and beyond the Dobrovolsky radius)-the authors suggested retrieving radon release (as well as methane, carbon dioxide and other geochemical fluids) indirectly, through remote sensing methods, from space-based observations of thermal infrared radiation, based on the LAIC model that correlates thermal anomalies with radon and other gas exhalations (Pulinets et al, 2006;Surkov, 2015;De Santis, et al, 2019b). However, the claim that closer to and on the eve of an earthquake a higher release should be observed is not yet confirmed and a statistical assessment of the true/false vs. positive/negative cases, through a reliable confusion-matrix based classification, is desirable.…”
