Abstract

This article presents the results of an assessment of seismic intensity increments depending on the engineering and geological conditions of arid areas in the Muynak district, located in the current Aral Sea crisis zone. Natural and man-made factors shaping the geological environment are examined, including geological structure, lithological and stratigraphic composition, soil physical and mechanical properties, and hydrogeological conditions. Based on the analysis of engineering-geological data, normative classifications of soils according to seismic properties and field research materials, seismic microzoning of the territory was carried out, identifying areas with initial seismicity (“0”) and zones with an increase in seismic intensity (“+1” and “–1”). It has been established that the most unfavorable conditions are associated with the spread of water-saturated dispersed soils of accumulative plains and the possible rise in groundwater levels to depths of 3–5 meters, which leads to a deterioration in the seismic properties of the foundations. The role of man-made factors caused by hydrocarbon extraction in altering the stress-strain state of the massif and the formation of deformation precursors of man-made earthquakes is demonstrated. The practical significance of the work lies in the possibility of using the obtained results in engineering-geological zoning, seismic hazard assessment and justification of the conditions for construction and industrial development of the territories of the Muynak district
