...Radon observations, both in soil-gas and in groundwater, revealed many precursory changes in its concentration before an earthquake (Talwani et al. 1980; Mogro-Campero et al. 1980; Fleischer 1981; Liu et al. 1984/85; Virk 1986, 1993, 1997; Segovia et al. 1989; King et al. 1993; Virk and Singh 1992; Igarashi et al. 1995; Heinicke et al. 1995; Virk et al. 1997; Singh et al. 1999; Chyi et al. 2005; Yang et al. 2005)....
