    Abstract. Crowning the tops of geological sections and occupying significant territories under favorable physical and geographical conditions, loess rocks are that lithogenous basis that has been very actively mastered by human society since ancient times. Loess rocks possess unique properties inherent only in this rock, which make them very vulnerable under the active technogenesis. As a result of technogenic impacts, massifs of loess rocks are degraded, which manifests itself as a complex chain of physical and chemical processes, sometimes very rapid and resulting in violation of the geo-ecological situation, irreversible changes in the loess-stacked massifs and formation of pseudokarst badlands. There are cases when the increase in the danger of loess pseudokarst under a high degree of vulnerability of structures led not only to high economic, but also social risk. On the example of objects in Tajikistan (the Yovon Valley), Russia (Western and Eastern Ciscaucasia), the urgency of the problem is shown. The main hazard indicators ranked by degree of importance and the subsequent calculation of the hazard factor have been introduced. Similarly, the loess arrays are ordered in terms of their vulnerability. Knowledge of the methodology for assessing the dangers of development of loess pseudokarst during the construction and operation of structures for various purposes, as well as for the development of previously not involved in economic activity loessial massifs, will make it possible to forecast the development of this formidable geological phenomenon and minimize high economic and social risks.
