Geochemical and geophysical monitoring of thermal waters in Sloveniain relation to seismic activity
Main Article Content
Abstract
Pre-seismic related strains in the Earth s crust are the main cause of the observed geophysical and geochemical
anomalies in ground waters preceding an earthquake. Posoc?je Region, situated along the Soc?a River, is one of
the most seismically active areas of Slovenia. Our measuring stations close to the Posoc?je Region were installed
in the thermal springs at Bled in 1998 and at Zatolmin in 1999. Since the beginning of our survey, radon concentration,
electrical conductivity and water temperature have been measured continuously once every hour. In
May 2002, the number of geochemical parameters monitored was extended to ionic concentration, pH and Eh,
which are analysed once a month. Before seeking a correlation between geochemical and geophysical anomalies
with seismic events, the influence of meteorological (atmospheric precipitation, barometric pressure) and hydrological
(water table of the Tolminka River) factors on observed anomalies were studied. Results at Zatolmin
showed that some radon variation during the period from June to October 2002 may be related to seismic activity
and not only to meteorological effects.
