Аnnotation: This text is about evidences of the seismotectonic activity of the South Coast Fault Zone that we have discovered in the Cape Fiolent region in the area a long of the 3.5 km. This seismotectonic activity area has northwest orientation and predominantly right-lateral displacement kinematics. Furthermore, we have obtain the value of the horizontal dextral slip with 55–60 cm. So magnitude of one of seismic events was estimated by M = 6.6–6.8, the epicenter of this earthquake localized in the Fiolent region on the southwestern border of the Herakleian plateau along the Black Sea coastline. Discovered earthquake in the Cape Fiolent region has dated by seismic ruptures in the walls of medieval “cave” churche on the cape Vinogradny and the temple on the cape Bezymyanny. They were directly in the source of the earthquake, which came to the surface. Destruction of archaeological objects occurred suddenly and at the same time, most likely in the middle of the 10th century. Also walls of the medieval monastery on the cape Vinogradny have deformations, which have dated according to archaeological data by the end of the 13th century (maybe 1292). Additional studies could to discover information about parameters of the epicenter of this late earthquake.
