Abstract
Large-scale ancient seismic dislocations represented by faults, landslides, and rockavalanches were discovered by remote sensing on the southeastern slope of the Andian Ridge in Dagestan. As a result of the strongest of these land- and rock-slides, dammed Lake Kezenoy-Am was formed. Essential structural features of the ruptures provide undoubted evidence of the seismotectonic origin of the latter. The kinematics of the ruptures (left-lateral strike-slip and thrust) is in conformity with geological data on neotectonic displacements in the Andian deep-seated fault zone. The acquired data allow considering this deep fault to be a major seismogenic structure and confirm the presence of a potential earthquake focus with M max = 7.0 disclosed previously in the Andian fault zone.
