Abstract

Landslides are one of the most destructive natural processes. The Loire landslide seems to be the reference object in this regard, it has absorbed 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 pruning) is also considered. The selected objects were examined by the geodetic and geophysical methods. Appropriate monitoring systems have been created.

Highlights

Slope processes are one of the most destructive natural processes that a person most often encounters during the mountainous areas’ development
The development dynamics, morphological and structural-lithological features, spatial characteristics and the static state of glaciers need to be investigated in detail and the opinion for the adoption of design decisions is given by the executive authorities
The ground method determines the actual state of a landslide, and the use of Global Navigation Satellite Systems (GNSS) and total station measurements provides an affordable and effective technology for measuring small deformations

Summary

Introduction

Slope processes are one of the most destructive natural processes that a person most often encounters during the mountainous areas’ development. The Loire landslide seems to be the reference object in this regard, it has absorbed 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. The Loire landslide hangs menacingly over one of the obstinate water flows of the North Ossetia-Alania region - the Ardon River and is a potential threat to a number of settlements and the Transkam Federal Highway. It was this landslide that became the primary goal of monitoring the Geophysical Institute of the All-Russian Scientific Center RAS. Two other objects of a smaller scale were selected for the study: the Zinsar landslide and a landslide in the area of the Fiagdon tailing dump, activated in 2019 as a result of cutting the slope
