The results of the latest research on active faults in Southern Dagestan, in the area of Derbent, using the paleoseismological and archeoseismological methods are highlighted. The zone of seismogenerating fault—the Derbent segment of the regional tectonic boundary between the mountain structure of the Greater Caucasus and the North Caucasian foredeep—is revealed. The last seismotectonic slip along the fault due to a strong earthquake led to the displacement of the early medieval city wall of Derbent. The magnitude of this event was M ≈ 7, and, therefore, the seismic shaking intensity was I0 ≥ IX. This seismic event occurred, most likely, in the 10th century AD.

杰尔宾特（达吉斯坦）中世纪早期堡垒墙的地震构造变形

突出了使用古地震学和考古地震学方法对杰尔宾特地区达吉斯坦南部活动断层的最新研究结果。发震断层带——大高加索山脉构造和北高加索前渊之间区域构造边界的杰尔宾特段——被揭示。由于强烈地震，最后一次沿断层发生的地震构造滑动导致了中世纪早期的杰尔宾特城墙的位移。该事件的震级为M≈7，因此地震震动强度为I0≥IX。这次地震事件最有可能发生在公元 10 世纪。
