Expanding knowledge about the origin and mixing of deep fluids and the water–rock–gas interactions in aquifer systems can represent an improvement in the comprehension of crustal deformation processes. An analysis of the deep and meteoric fluid contributions to a regional groundwater circulation model in an active seismic area has been carried out. We performed two hydrogeochemical screenings of 15 springs in the San Vittorino Plain (central Italy).

Anomalies in Radon (222Rn) concentrations prior to earthquakes have been widely documented in seismogenic areas worldwide, but questions about their predictability remain largely unanswered. Even if it is not universally accepted, the analysis of the high-resolution time series of Rn (222Rn) concentrations in groundwater, air and soil has been proposed as a suitable method to identify seismic precursors.

The aim of this study was to identify potential patterns of hydrogeological and geochemical changes in response to seismic activity, including possible variations of ion concentrations, gas compositions, and isotopic ratios in groundwater. Different monitoring areas in Central Italy

Wedge-top basins can provide highly sensitive information on the uplift and erosion history of an evolving collisional belt, but their burial and thermal history has generally been neglected because their siliciclastic infill records the very low temperature history, which is difficult to detect. This paper provides an integrated approach for defining the first order tectonic events shaping the southern Apennines in Neogene times through the study of a wedge-top basin.

In this paper, we present an integrated approach, for assessing the condition of an ancient Roman building, affected by rising damp and cracking phenomena. The combination of high-resolution geophysical methods, such as seismic and electrical tomography, with biological information, allowed a more detailed evaluation of the state of conservation of the masonry building. A preliminary three-dimensional electrical survey was conducted to detect the existing building foundations and to determine the variation of the resistivity in the ground.
