Totally about 23,000 landslides were identified in the territory of Ukraine. Experimental and analytical studies of slumps in the Central Livadia landslide system were carried out with the aid of the ZSUV monitoring system. Experimental data were obtained concerning impact of natural seismic factors on the Central Livadia landslide system and on the Palace itself. The South-East wing of the Livadia Palace continuously vibrates relative to a certain midposition. The increase of the amplitude of the faqade deviation from the midposition may be caused by activation of slopes as a result of additional subsidence and ground water rise due to local earthquakes in the Black Sea and because of some other factors.展开更多
