This case study presents the results of a geophysical survey that was carried out in 2008-9 at Omalos plateau in Chania, Western Crete, Greece. During this survey we applied seismic methods as well as electrical tomography in order to image the active karstic structures of the Omalos polje. The resistivity and seismic velocity sections image properly karstic structures such as a doline to the south. In addition the geoelectrical sections outline the metamorphic carbonates relief (Tripali unit and Plattenkalk group), which appears highly irregular. At Omalos polje the thickness of post-Mesozoic deposits (terra rossa, clays, sands and gravels) ranges from 40-130 m.
