It’s location in the central part of the City of Batumi stipulates an importance of intensive research of fenomena. The natural growth of the cape towards the sea was stopped in 30-40-ties of last century, when it’s frontal part closely approached the head of the Rv.Chorokhi submarine canyon. The major part of debris ,washed down by river flow, accumulate on the mouth offshore submarine slope, stays there for some time in stable condition and depending on the stability conditions for sediment deposit layer, either is gradually washed out by coastal currents, or is fallen down as discrete parts or blocks through underwater gorge channels. The stability conditions of submarine sediments are disturbed by changes in the tangential reaction between soil particles or blocks, increased pore pressures, storms, instability of the underlying rocks, structural motions, tsunamis, earthquakes (e.g. stability conditions has been violated by strong earthquake occurred in Turkey on 14-th of January,1999). Investigation of the stability conditions of the bottom sedimentary layers deposited inside the submarine gorge (channel) has been undertaken on the base
