Variation of Soil Gas 222rn/220rn Concentration Ratios Along the Pinarbaşi Segment of Izmi̇r Fault

Abstract

Abstract Measurements of 222Rn and 220Rn activity were carried out along the Pınarbaşı segment of the Izmir fault (IF) to get new information on the Izmir Fault (IF) and its seismicity. İzmir Fault is one of the most important active tectonic structures in Turkey's Active Fault Map. Due to very intense urbanization, there is not enough information about the fault. This study also discusses the usability of the 222Rn/220Rn ratio as a geodynamic precursor.
