Abstract The area inside and around the church of Kapnikarea in Athens (Greece), was explored by means electrical resistivity tomography (ERT). ‘Flat base’ electrodes were used exclusively because survey had to be fully non‐destructive. performance ‘flat satisfactory, leading inversions small root mean square (RMS) errors reliable subsurface images, which checked against existing borehole logs. High‐resistivity anomalies observed beneath floor church. They are attributed possible voids,...
ABSTRACT This paper describes the application of three‐dimensional electrical resistivity tomography (ERT) in urban environments to detect wall foundations or similar structures. In this study, a specific measurement strategy based on optimized 3D arrays with surface electrodes is proposed and tested. As type survey can be used for archaeological prospection, special design was chosen make as non‐invasive possible. The ERT scheme therefore layouts that placed electrode lines each side wall....
The M w = 6.4 July 26, 2001 Skyros (North Aegean, Greece) earthquake struck the submarine western end of Northern Aegean Sea causing damage in nearby Island. It occurred on a left‐lateral NW‐SE trending strike slip fault, oriented transverse to dominant dextral strike‐slip faults that are present area, appearing mark boundary between them and E‐W normal Greek mainland. Foreshock activity started 5 days before mainshock, intense aftershock followed main rupture plane off fault. seismogenic...
ABSTRACT The application of flat‐base electrodes to geoelectrical measurements is examined. This study motivated by the inability apply techniques in environments where conventional spike cannot be inserted into ground. performance examined various environments, using different measuring modes. It shown that can satisfactorily used most cases, producing data are almost identical obtained standard electrodes. Several case studies urban locations Greece, have been successfully employed, also...
A tumulus is a construction erected to cover tomb. Some tumuli are impressively massive and may conceal architectural masterpieces. Seismic refraction employed locate the tomb allow selective excavation without destroying tumulus. The detectors spread along circular profile on periphery of tumulus, acoustic waves generated its top. Time delays observed in arrivals headwaves reveal position monument. not caused by monument itself, but an effect presence ramp that was dug undisturbed soil help...
Abstract Detailed and precise measurement of the Earth's gravity field (microgravity method) can be effectively used for detection quantification subsurface voids and/or cavities. There exist a variety successful applications microgravity method in near surface geophysics, namely geotechnical, environmental archaeological prospection. Using state‐of‐the‐art ‘microgal’ relative meters, cavities several metres each dimension (positioned at similar depth) detected interpreted. Such objects...
Abstract The geophysical investigations aiming to image the interior of huge tumulus Kastas in Amphipolis northern Greece commenced on November 2014 and continued sporadically until first months 2017. electrical resistivity tomography (ERT) method was exclusively employed both conventional innovative schemes. Due immense size tumulus, an irregular grid established whereas regular grids ERTs were a small terrace created by excavations at south extremity. Also, typical two‐dimensional (2D)...
ABSTRACT The surviving Tunnel of Eupalinus comprises one the greatest engineering achievements ancient Greeks. tunnel itself (1036 m long) was carved in sixth century bc through solid rock by digging from both ends and advancing to central meeting position. method for achieving two simultaneously branches is still unclear. lining shows damage, indicating instability mass, presumably due tectonic action. At certain points, damage becomes more severe partial collapses are observed. Therefore,...
P. Tsourlos, G.N. Vargemezis, I. Fikos1 and Tsokas present four case studies of geoelectrical methods to investigate different types landfills in Greece. There is a growing demand for monitoring both operating rehabilitated municipal solid waste (MSW) landfills. In this framework, geophysical investigation particularly techniques are considered as valuable tool environmental management. The DC probably the most popular applied landfill investigations (Meju, 2000). conductive signature...
