Modeling of the relationship between soil radon gas (222Rn), earthquake and meteorological variables

The measurement of 222Rn concentrations in soil and groundwater is used to monitor the stress change in fault lines due to seismic and tectonic activities. Geochemical behavior of underground gases depends on their chemical structure. Other materials may also accompany migration of inert gases in the earth layers. Thus, gases emitted from the depths of the earth can provide useful information about the upper layers. 222Rn shows more reaction to changes in earth stresses during seismic activity than other gases. Therefore, it is one of the most effective parameters used in earthquake prediction studies. In order to see the physical or chemical changes of any variable, the use of 3-dimensional images is helpful in making useful interpretations. In general, these images are based on latitude and longitude and the observed parameters are observed. The best configuration and interpretation of these changes is done in 3-dimensional with contour maps. In this study, 222Rn concentrations taken from Dereköy (Kargı, Çorum) station on the North Anatolian Fault Line were studied. The change of 222Rn with earthquake and meteorological factors was investigated and 3-dimensional map drawings were obtained. Key Words: Radon, Seismic Activity, Meteorological Factors, Earthquake
