As a result of engineering and geophysical surveys on selected areas of Zmiiny Island, new and confirmed locations of some known faults were discovered. Seismic studies were conducted on the island to study the structure of the sedimentary cover, the weathering zone, and the integrity of the bedrock. During the interpretation of seismic data obtained on the island, the structure of some faults completely covered by the sedimentary cover was studied in detail. The degree of opening of the faults (width) and their internal filling were determined. The orthogonal scheme of the location of seismic profiles allowed us to establish the azimuths of the strike of the detected faults that pass through the entire island. The azimuths of tectonic faults in the Black Sea coincided with those on the island. Thus, the island, which is at the top of the fold, was under the influence of tectonic movements that formed the Golitsynskyi, Istrian, and Trotus Faults.
