Investigation of the relationship between of the Radon Concentration Variation in Reyhanshahr Hot Spring and Earthquakes with D/R >0.5 in that Zone

Previously earthquake prediction in Iran and world was down with various methods. Result was shown that  the 17-25 days before D/R > 0.5     earthquakes ,  the  FD-RC  was varied rapidly large than standard deviation  in  Reyhan Shahr (Zarand-Kerman) hot spring .therefore  the FD-RC is a powerful  parameter for  earthquake prediction.in this research the experimental data of radon of  Reyhan Shahr(Zarand-Kerman)   hot spring in 2011/12/03 -2012/03/02  time interval was taken from Dr.Negarestani et al  KGUT(Kerman Graduate University of Advanced Technology)  earthquake prediction center. Result was shown that the 15-17 days before D/R > 0.5 earthquakes, the FD-TR was varied rapidly large than standard deviation in Reyhan Shahr (Zarand-Kerman) hot spring. Possibility of earthquake prediction was shown that the D/R > 0.5 earthquakes will happen in 20 – 26 Bahman 1395 in Reyhan Shahr (Zarand-Kerman) zone. Therefore the FD-TR is a powerful parameter for earthquake prediction.
