The detection of cavities in urban areas is important to prevent different causes of accidents related to possible collapse. The cavities are also interesting targets to archaeologists because forgotten cavities are potential sources of material revealing past uses. These cavities are of different sizes, of anthropogenic origin or not, in an outdoor setting or under buildings. Their size and the physical properties of the external environment in which they are located, allow the use of different geophysical methods. We focused on the use of two of them, Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT), to locate and determine cavities in the near subsurface (first 6 meters). GPR data are sensitive to variations in ...
