Description :
The earthquake that struck L’Aquila on April 6 2009 directly affected the Gran Sasso aquifer. Co-seismic and post-seismic changes in groundwater discharge and in hydrochemistry, possibly induced by the earthquake, were observed. Spot and monitoring measurements of the spring discharge, of water table level and of the main physico-chemical parameters of spring waters (T, pH, electrical conductivity, major ions and 222Rn) were thus carried out to determine the effects of the L’Aquila earthquake on groundwater at regional and local scale, to be compared with available data collected since the 1990s. Short- and mid-term effects have been observed in the groundwater flow at recharge and discharge areas. A conceptual model of the earthquake consequences on the Gran Sasso aquifer is proposed in this article. - (NF)
