“…The integration of different geophysical techniques can remove ambiguities on interpretation of geophysical models, increasing the degree of accuracy of the physical and chemical parameters reconstruction [11,12]. An estimation of the physical and mechanical parameters of the structural element can be given by the Seismic Tomography, focused on the cracking-prone zones [13] or on the investigation of the foundation structure and ground material of ancient buildings [14]. Another technique that has been used in a fully non-destructive mode is the electrical resistivity tomography (ERT) method.…”

“…As with other recent applications of seismic tomography in similar archaeological environments but quite different in their details, such as the search for burial structures in a monumental tumulus (Polymenakos et al, 2004a) and the investigation of the foundations of a Byzantine church (Polymenakos et al, 2004b), the results of the present work provide evidence that seismic tomography, when used in the particular manner and under the particular conditions described above, can provide detailed and accurate images of the subsurface and thus can be considered as an attractive exploration tool for the investigation of prehistoric and other types of archaeological sites in a non-destructive manner.…”

Seismic tomography is applied in the exploration of the subsurface of a prehistoric site for remains of human structures.Prehistoric sites are important foraccessing information on human history in times of limited written evidence. Knowledge of the subsurface character and pattern of possible structural remains can be of great help in excavation design and assessment. A case history of the application of seismic tomography at Palamari prehistoric site, Skyros Island, Aegean Sea,Greece, is presented. Energysourcesandrecordersareplacedonthegroundsurface.Traveltime dataareanalysedandprocessed with three-dimensional tomographic inversion software. Seismic velocity images of the subsurface are constructed. Modelling of the subsurface is used to improve the interpretation and assist in the evaluation of the significance and reliability of the results.Velocity variations are known to correlate well with the lithological character of the earth materials, thus providing important structural andlithologicalinformationofthe subsurface.Theresultsshowagood correlation, intermsoflocation, geometry and dimensions, with expected and excavated real dimensions and pattern of the foundation and near-surface structure

“…Intelligent recording layout design and the use of sources/receivers adapted to the site conditions will assist in a better imaging of the subsurface and of man‐made structures in particular, as has been already observed in other tomography applications (Polymenakos and Papamarinopoulos ; Polymenakos et al . , , ).…”

We apply seismic traveltime tomography in an investigation of the subsurface of a geoarchaeological site at Chatby cemeteries (Alexandria, Egypt). We are interested in obtaining information about the geological structure and the remains of man‐made structures. Energy sources are placed at the surface and recorders are distributed vertically in an underground location. Traveltime data are inverted with a three‐dimensional tomographic algorithm. Inversion results are evaluated and interpreted with the aid of independent geophysical and archaeological information, and various tests are carried out with different initial velocity models and synthetic traveltimes. The inversion results show good correlation with the estimated geological structure, in particular at deeper levels, as suggested by independent geophysical and archaeological information and later confirmed by excavation. The depth and variations of the bedrock surface are satisfactorily imaged. Indications of possible man‐made structures are presented and discussed. Shallow velocity features are evaluated and interpreted using tests with synthetic traveltimes. The main goal of imaging the deeper structure was successful. As inversion tests with different initial velocity models indicate, the subsurface structure and the complexity of data information in this particular case are better handled when using a single‐layer model than when using an average two‐layer model. The single‐layer model allows for a more versatile velocity variation and raypath distribution, while the two‐layer model leads to an inversion result that is considerably influenced by the initial velocity distribution. Enhancement of particular aspects of the single‐layer inversion result can be derived with the use of an initial velocity model, that permits a gradual increase of velocity with depth. The gradient model improves the raypath distribution and limits velocity artefacts. The resulting images can assist in the assessment of the archaeological potential of a site, particularly in excavation design, in a non‐destructive manner. They can be also of great value in other applications, for example in engineering works, when detailed information on the subsurface is sought in areas of restricted access.
