The use of geosynthetics in earthquake engineering has gained prominence due to their effectiveness in enhancing structural stability, mitigating seismic-induced failures, and improving soil performance. This study conducts a systematic review of geosynthetics applications in earthquake-prone regions using Latent Dirichlet Allocation (LDA) in MATLAB, analyzing abstracts from the Scopus database. Findings reveal that geosynthetics, such as geogrids, geotextiles, and hybrid systems, significantly improve stability by reducing structure deformation, mitigating liquefaction risks, and distributing loads. Innovative reinforcement techniques like expanded polystyrene (EPS) geofoam, geosynthetic-encased stone columns, and geocomposites demonstrate effectiveness in reducing seismic displacements and mitigating liquefaction by delaying pore pressure buildup. Numerical and experimental studies validate the critical role of optimized configurations in addressing dynamic challenges, while probabilistic modeling highlights the importance of adaptive designs to enhance resilience. Despite advancements, gaps such as limited field validation, inadequate exploration of seismic effects on geosynthetic configurations, and insufficient data on dynamic soil-reinforcement interactions remain. Addressing these gaps ensures progress in geosynthetic applications for earthquake engineering. This review highlights the potential of geosynthetics in advancing geotechnical solutions and sets a strategic direction for future research to strengthen infrastructure resilience in seismic regions.
