The article is devoted to the identification of geological problems of the coastal zone of the North-Western Black Sea region, namely, destruction and landslides, as well as the study of their consequences.The main recreational area of the North-Western Black Sea coast is the beaches located on the Black Sea coast, rivers and estuaries, which are the most popular places for recreation and treatment of local residents and guests of the Black Sea coast. At the same time, one of the main problems of the coastal zone of the North-Western Black Sea region is destruction and landslides – a widespread geological phenomenon. The main causes of landslides are: groundwater; undermining the banks of rivers, lakes, seas and other bodies of water; improper excavation work; extensive construction work on the coast; lack of reconstruction or overhaul of the coastal zone.For several millennia, the steep shores of the Odessa Bay were undermined by such a natural phenomenon as landslides associated with the peculiarities of the geological structure of the coast. In Odessa, this led to a series of large landslides: in Otrada (1897); on Lanzheron (1918); in the area of the Marazli dacha and the Chkalov sanatorium (until the 1960s); at the 11th Fontana station (1936) and the 13th Fontana station (1956). One of the most large-scale and destructive landslides in Odessa was the landslide of 1918, which practically destroyed Chernomorskaya Street – the entire odd side of the street disappeared.Since the beginning of the 1960s, large-scale and long-term (more than 20 years) coastal protection works have begun, which have retained a huge margin of safety, but extensive construction work on the coast and the lack of comprehensive reconstruction or overhaul of coastal protection works can lead to numerous landslides. As a result, not only Odessa beaches, namely the recreational zone, but also a part of the historical and architectural area of Odessa, located on the coast, can be destroyed.

Рассматриваются геологические проблемы береговой зоны Северо-Западного Причерноморья, а именно – разрушение и оползни, а также изучение их последствий. Основными причинами возникновения оползней являются: подземные воды; подмыв берегов рек, озер, морей и других водоемов; неправильное производство земляных работ; обширные строительные работы на побережье; отсутствие работ по реконструкции или капитальному ремонту береговой зоны. На протяжении 1960 – 80-х годов были проведены масштабные и длительные берегозащитные работы, которые сохранили огромный запас прочности, но обширные строительные работы на побережье и отсутствие капитального ремонта берегозащитных работ, могут привести к многочисленным оползням. В результате чего могут быть разрушены не только одесские пляжи, а именно рекреационная зона, но и часть историко-архитектурного ареала Одессы, расположенного на побережье.
