Popis: SUMMARY It has been suggested that temporal variations of radon (Rn) concentrations in various media may be used as a possible predictive indicator of seismic activity. However, observed Rn measurements are a function of a number of diierent physical processes including seismic activity. This paper describes a generalized approach to removing ‘noise components’ from the observed data to leave a residual component of radon concentration that re£ects geodynamic processes at depth. The approach is demonstrated using data gathered in Israel at the time of the 1992 October 12 Giza earthquake in Egypt.
