Аннотация:Ancient Gorgippia is in surrounding of known seismogenic zones: Northern Black-Sea, Kerch’,Southern Asov. All of them are stretching below the water and only few secondary faults reach the surface inthe coastal zone. Also in the surface – near ancient city there are seismically active faults and fl exure zoneswhich can be the sources – generators of the strong earthquakes. Our study in the walls of ancient Gorgippiahas revealed a number of seismically induces deformations and destructions: systematic tilts and shifts of upperparts of the walls, as well as their arch-like warping in plan; shear ruptures of the walls; rotations of wallsand other building elements around vertical axis; squashing of water wells’ mouths and stems. Some of mentioneddeformations can be formed during strong historical earthquakes in III and I centuries BC, as well as inI and III century AD. There seismic events were accompanied by local destructions and fi res. Summarizing allmaterials on historical earthquakes of the Taman’ Peninsula one can conclude that regional seismic potentialis determined by a possibility of М ≥ 7.0 crust earthquake occurrence with average recurrence interval – oneseismic event in few hundred years. Seismic oscillations in the source zone from such natural events are I0 = IXor even more
