The area of Tajikistan is 143.1 thousand km2, while about 93% of its territory is occupied by mountains, the maximum heights of which reach more than 7000 m above sea level. The rest of the country (7%) is plains and valleys with heights from 300 to 1000 m above sea level. Such a significant range of heights is explained by the location of the study area in the junction zone of the Tien Shan fold system and the Alpine-Himalayan belt and leads to a wide variety of geological, hydrogeological, landscape-climatic and seismic conditions, analysis of the consequences of destructive earthquakes is of great importance for solving scientific and practical problems in the field of seismology, as well as problems of earthquake-resistant construction. The analysis of consequences of destructive earthquakes is important for solving scientific and practical tasks in the field of seismology and problems of earthquake engineering. One of the main sources of seismic resistance assessment of buildings and structures, along with theoretical and experimental studies, is engineering analysis of the consequences of strong earthquakes. This article deals with the effects of earthquakes on the earth's surface. The example of the following devastating earthquakes that occurred in Tajikistan, the impact of these seismic events on various types of residential buildings built from local materials is considered, and the main reasons for the observed nature of deformations and destruction are discussed.
