    Abstract. A large part of the territory of the Russian Federation is located in the zone of possible earthquakes with an intensity of 7 points (MSK-64) and more, which can be accompanied by secondary earthquake-induced dislocations. Among such dislocations the most hazardous are earthquake-induced landslides. The current normative documents regulating the design of industrial and civil objects under the seismic impact don't consider the issues of assessment of the development of seismic-gravitation dislocations. On the example of a model slope, the article qualitatively evaluates its stability with the use of quasi-static and dynamic analysis; values of the stability factor are obtained. The value of the stability factor calculated on the basis of quasi-static analysis is slightly less than its minimum values calculated on the basis of dynamic analysis. The marked differences are the first percentages. The conservatism of the obtained quantitative estimates of the slope in the conditions of seismic impact is shown. This requires additional analysis in order to justify measures to ensure the stability of the slope in seismic conditions for industrial and civil buildings and structures.
    Key words: earthquake-induced landslides, quantitative assessment of slope stability, quasi-static analysis, dynamic analysis, seismic impact.
