GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.2 GNGTS 2024 EM and ERT techniques has proven to be an essental tool in guiding archaeological digs to discover buried remains, at the Akragas site. The processing of the data acquired have identfed anomalies in the subsurface characterized by signifcant variatons in physical parameters. Given their physical and geometrical characteristcs, such anomalies were atributed to buried structures of anthropogenic origin. Based on the results obtained by ERT surveys, an inital test excavaton was conducted in one of the areas identfed by the geophysical surveys. Excavaton revealed the presence of an unknown building of potentally crucial importance to the religious topography of the area under investgaton. The integraton of geophysical techniques with traditonal archaeological methods contributes to a more efcient, cost-efectve, and informed approach to archaeological research and preservaton.
