Geophysical Investigation of Earth-fissures by Means of ERT

Earth fissures tend to be an issue of increasing concern, especially at the margins of sedimentary basins at semi-arid areas, since they cause damage to houses, commercial buildings, or infrastructure. In this work we present case studies involving relatively high resolution ERT measurements carried out at areas of earth fissures at the margins of sedimentary basins in Greece. From the results presented in this work, it is obvious that the application of the technique of electric tomography provides important information on the structure of subsoil in the investigated regions and is capable to locate regions in which earth fissures are likely to take place.
