The 222Rn activity concentration in ground water from four boreholes was investigated from January 2006 to June 2008. The boreholes are situated in the region of the Astronomical and Geophysical Obser...
Time-scale invariant changes in atmospheric radon concentration and crustal strain prior to a large earthquake
Time-scale invariant changes atmospheric radon concentration crustal strain earthquake
2009/11/2
Prior to large earthquakes (e.g. 1995 Kobe earthquake, Japan), an increase in the atmospheric radon concentration is observed, and this increase in the rate follows a power-law of the time-to-earthqua...
