A detailed geophysical survey was carried out at Chania airport located at the north-west part of Crete, Greece in order to detect cavities in carbonate rocks. This survey combines electrical tomography and borehole data from Chania airport where new buildings are planned to be constructed. The site mostly consists of recrystallized carbonate rocks belonging to Trypali unit. Electrical resistivity tomography applied in dense grids at Chania airport provided images of the subsurface which conducted a borehole program for the detection of karstic forms in the carbonates. At the area under investigation according to resistivity imaging as well as borehole and surface geological data, the formations are mostly characterized as highly fractured. The size of the existing voids ranges from 0.5m to 6m.
