Geochemical and geophysical monitoring of thermal waters in Sloveniain relation to seismic activity

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