## 1 Introduction  
The analysis of approaches to the assessment of natural hazards of various nature, used in the world, showed the following. There are no generally multi-hazard approaches: the spatial representation of natural disasters must consider all types of hazards with the help of a multi-risk approach at all spatial levels (regional and local). With few exceptions (France, Italy), the multi-risk approach is not used due to the differences in the responsibilities of sectoral planning departments for different disasters. The intensity of the attention given to natural disasters usually depends on the experience of recent catastrophic events rather than the occurrence of catastrophic events in the more distant past (the Kolka glacier collapse in 2002, which repeated the 1902 collapse scenario). As a result, risk assessment and management are focused on more frequent hazards (river floods, avalanches, forest fires) than on less frequent events. This leads to a tendency to underestimate the hazard and risk posed by extreme events. At present, spatial planning plays only a minor role in risk management: at the regional level, various sectoral planning departments are responsible for natural risk management. Regional planning is often just one of the subsidiary entities charged with the duty of ensuring the implementation of measures that are carried out by sectoral planning units. Geohazards can be formed through continuous natural processes, such as weathering or erosion [1], though they are predominately created and accelerated by anthropogenic activity [2]. Geohazards that have occurred, and been thoroughly investigated to determine their source, can be used to predict vulnerability in similar formations and situations elsewhere [3] and to extend this knowledge to areas not yet developed. There are a number of works where geohazard mapping has been developed using multi-form, digital image data, permitting a regional assessment of risk concerning slope instability. Slope angle and slope aspect data were derived from a digital elevation model (DEM), produced from stereo air photographs. The geohazard map was then compiled by merging digital slope data with geotechnical characteristics, using map algebra within a geographic information system (GIS) [4; 5; 6; 7]. An important aspect of the geohazard study is identifying the temporal and spatial distribution of zones liable (prone) to movement, including the location of potential slip surfaces. The methodology adopted for the landslide hazard donation of the study area includes the various geoinformatical tools comprising geographical information system (GIS) technology and the satellite remote sensing (RS) techniques [8]. Geomorphological parameters (elevation, slope, aspect, curvature) and drainage are widely extracted from a DEM based on the Shuttle Radar Topography Mission (SRTM) [5]. Furthermore, the use of GIS facilitated the extraction of geomorphic and hydrological parameters required for susceptibility assessment. More detailed DEM may be obtained using low altitude UAV photogrammetry [9]. All of the mentioned techniques are itself of data collection and should be supplemented by geophysical data, expressed in the manifestation of processes in physical fields, and on the other hand, the results of their interpretation in the form of tectonic schemes, fault schemes, geological structures, and geotechnical parameters. A methodology for the comprehensive assessment of geological hazards of various nature on the basis of the method of expert assessments is proposed in the present paper. The relevance of the topic is caused by the fact that the territory of North Ossetia is prone to the destructive effects of almost all known types of hazardous geological processes that can lead to the death of people and enormous material losses, having a significant impact on the socio-economic situation and safety of the territory of the republic.
