<p>Seismic geotechnical engineering has undergone significant advancements over time; however, the recurrence of catastrophic failures due to seismic events underscores the critical necessity of assessing the seismic stability of geotechnical structures to ensure their safe design and performance. This paper covers the seismic analysis of different geo-structures with emphasis on the bearing capacity of the ring foundations, impact of blast loading on buried pipelines, vertical expansion of the landfills, tensile strength of the reinforcements in waterfront retaining structure, active earth pressure of the retaining walls, etc., by numerical or suitable analytical approach. The numerical simulations for these analyses were carried out using ABAQUS Cae or by a well-defined limit equilibrium approach using pseudo-static analysis in MATLAB. Observations indicated the devastating effect of the seismic forces on the geotechnical structures. The horizontal seismic acceleration coefficient (<i>k</i>_<i>h</i>) has a major impact on the degradation of soil strength compared to the vertical acceleration coefficient (<i>k</i>_<i>v</i>). The detailed implications of these observations are discussed in their respective sections, providing critical insights into the behavior of geotechnical structures under seismic loading conditions. This study highlights the importance of integrating robust numerical techniques and analytical approaches to develop resilient geotechnical designs capable of withstanding seismic forces.</p>
