Abstract

According to the variety and the intensity of dangerous natural processes occurence, the Greater Caucasus can serve as a natural laboratory, where geodynamic processes of a different order proceed continuously. One of the most destructive natural processes are the landslides. A reference object in this regard is the Luar landslide, which has included all the extreme features of landslide structures known in the Central Caucasus, but has not revealed the secrets of its static state, the determination of which is the most important task of the scientific research. An active landslide formed as a result of anthropogenic activity (slope cutting ) is also considered. The mentioned objects were examined by the geodetic and geophysical methods. Appropriate monitoring systems have been created.

Highlights

Natural processes of an endogenous and exogenous nature, representing the varying degry of hazard for the population, are a commonplace of the planet active life
According to the variety and intensity of dangerous natural processesmanifestations, the Greater Caucasus can serve as a natural laboratory where geodynamic processes of a seismotectonic nature continuously occur on a continental scale, due to the collision of the Scythian plate and southern microplates supported by the Arabian plate, as well as on a regional scale, caused by the activation of seismicity in the zones of deep faults
One of such unstable structures, widely developed in the mountainous part of the Greater Caucasus, are landslides, which are long-term forming geological objects, the development dynamics, morphological and structural-lithological features, the spatial characteristics and static state of which can be studied in detail and it will be possible to give a reasonable conclusion for making design decisions by the executive authorities
