Research into landslide processes in the coastal zone of the Takhtakorpureservoir using vertical electrical sounding method (the southeastern slope of the Great Caucasus)

Landslide-prone areas on the coastal zone of downstream Takhtakorpu reservoir located arid-hilly part southeastern slope Great Caucasus mountain system (Azerbaijan) were investigated using vertical electrical sounding (VES) method. The entire research area is geologically active. It complicated by seismicity (with an intensity 8—9 points MSK-64 scale), (uplift Earth’s crust about +6 mm/year) and horizontal (4 ± 1 mm/year, generally north-north-east) movements, landslides (in more than 5 centers) as well Gaynarja mud volcano, in form hill ≥100 m diameter with griffins. Tectonically, volcano timed to consolidated anticline same name, which currently right-bank zone, closer water reservoir. Therefore, erupted products come into contact aquatic environment. geological structure territory dominated rocks Pliocene Productive Stratum (N2). With respect lithology, they consist clays argillaceous rocks. Groundwater occurs sporadically, a total salinity 7 g/l filtration coefficient 4 m/day. Geological sections studied depth 40 m, thickness composition individual layers described. 3D models study developed completely arbitrary cut also along X, Y Z axes. was revealed that composing section region are subject impact plicative dislocations due geodynamic processes. assumed mainly formed at eluvial-deluvial deposits bedrocks. One main reasons for formation landslide phenomena, apparently, associated steepness slopes their constituent rocks, absorbing atmospheric precipitation become waterlogged. depths slip planes blocks direction body determined.
