“…The profiles consisted of 48 electrodes, spaced 1.25 m; apparent resistivity data were acquired using both Wenner-Schlumberger and dipole-dipole configurations to obtain adequate lateral and vertical resolution and good signal strength. We employed 10cmx10cm flat base copper electrodes [Tsokas et al 2008] coupled to the soil with conductive gel to perform a totally non-invasive ERT investigation ( Figure 5). The injected current range was 50-500 mA.…”

“…ERT has been extensively employed in various cases such as in archaeological, geological and hydrogeological studies (Tsourlos et al, 2003;Tsokas et al, 2008b;Vargemezis et al, 2007, Ogilvy et al, 2009Vargemezis et al, 2009). …”

Ground penetrating radar (GPR) and electrical resistivity tomography (ERT) surveys have been carried out in the city centre of Thessaloniki (N. Greece), for investigating possible locations of buried building foundations. Geophysical survey has been chosen as a non-destructive investigation method since the area is currently used as a car parking and it is covered by asphalt. The geoelectrical sections derived from ERT data in combination with the GPR profiles provided a broad view of the subsurface. Regarding ERT, high resistivity values can be related to buried building remains, while lower resistivity values are more related to the surrounding geological materials. GPR surveying can also indicate man-made structures buried in the ground. Even though the two geophysical methods are affected in different ways by the subsurface conditions, the processed underground images from both techniques revealed great similarity. High resistivity anomalies and distinct GPR signals were observed in certain locations of the area under investigation, which are attributed to buried building foundations as well as the geological structure of the area.

“…In these situations GPR is usually the easiest and fastest method (Leucci, 2002;Nuzzo, 2004), although occasionally lowinvasive or non-invasive ERT techniques, using thin nails or base-plate electrodes, have also been attempted for indoor investigations (Nuzzo and Quarta, 2005;Tsokas et al, 2008).…”

Hierapolis, Denizli, Turkey, was one of the most important Hellenistic-Roman cities in Asia Minor.Located about 250 km east of Izmir, the area is a UNESCO World Heritage Site because of its magnificent archaeologicalremainsandthewhitetravertine poolformationscreated byitspeculiargeothermal setting. The Italian Archaeological Mission in more than 50 years of activity in Hierapolis has brought to light and restored important vestiges of the ancient city, helping to understand the urban layout in the various epochs of its development. In 2001^2003 geophysical surveys were performed by the University of Lecce in several areas inside the archaeological site of Hierapolis to support the archaeological excavations.This paper reports the results of the integrated geophysical surveys performed in 2003 inside the Martyrium of Saint Philip, a mausoleum built on the place where it is believed that the Apostle was martyred. Ground-penetrating radar (GPR), electrical resistivity tomography (ERT) and magnetic gradient investigations were carried out in the central octagonal room, whereas the accessible lateral rooms were surveyed with GPR and occasionally ERT.The acquisition was performed along a series of closely spaced lines and the processed data were visualized as two-dimensional vertical sections (GPR), map view (magnetic gradiometry), depth slices or threedimensional volumes (GPR and ERT) to allow an integrated interpretation of the geophysical results. The analysis of the geophysical datasets revealed a series of anomaliesin both the central andlateral rooms that could be ascribed to the building foundations and to other possible archaeological structures, probablyrelated to earlier stagesofthe sacredbuildingandto tombs, aswellasotheranomalies (voids, fractures) of presumable natural origin.
