Аnnotation: The Sary-Bulun archeological sites located along the Great Silk Route during medieval time had been studied. The study has revealed a number of the deformations of seismogenic origin: tilts, shifts, collapse and lateral bends of walls, as well as long fissures in corner parts of the premises. Judging by archeological artifacts, an age of the seismic event is end of XII - beginning of XIII AD. Judging by degree of damage, the intensity of the ancient earthquakes was I ≥ VIII according to MSK-64. The source of the seismic oscillations was apparently of the ruptures cutting the active Boz-Barmak anticline. Studied archeological sites are located on western limb of this anticline structure. During medieval time the Sary-Bulun settlements were the largest metallurgic centers of the Issyk-Kul depression and thus they have a great significance for a study of the industrial processes then.
