Uranium (U) groundwater anomalies, detected before the L'Aquila earthquake (April 6th, 2009), represent a key geochemical signal of a progressive increase of deep fluids fluxes at middle–lower crustal levels associated with the geodynamics of the earthquake. Although the analyses performed in association with the seismic pattern around Gran Sasso National Laboratory and the geophysical and geochemical patterns of the Gran Sasso aquifer supported this hypothesis, a new approach for time series analysis has been developed for event screening categorisation and to highlight U as possible strain meter in geodynamical processes, particularly those which characterise active normal faulting.
