Abstract This research addresses the imperative task of effective disaster mitigation planning for significant earthquakes, specifically focusing on the Shamkir-Mingachevir reservoir region. The complexities of seismic risk assessment involve the intricate interplay of geological, geotechnical, and environmental factors. The character of propagation of seismic waves is influenced significantly by local site conditions, shaping the observed intensity of ground motions at the surface. The term “site effects” is central to this research, signifying the amplification of seismic waves influenced by distinctive geological conditions. The results indicate that soils with lower shear wave velocities exhibit lower peak ground accelerations at the surface. However, the study highlights the susceptibility of softer soils to nonlinear effects, emphasizing the need to consider the composition of local soils in developing seismic safety measures. The separate study of resonant frequencies of the soil-structure system is crucial to mitigate resonant effects during earthquakes. This approach facilitates the development of accurate and tailored building standards aimed at safeguarding infrastructure and ensuring safety in seismic zones.
