Seismic site response analysis is crucial for geotechnical engineers as it defines the dynamic behaviour of soils and rocks subjected to earthquake-induced ground motion. In this research work, an extensive site response analysis of the Famagusta region located in the eastern part of Cyprus, known for its seismic activity, is conducted to investigate the amplification and attenuation characteristics of the local site conditions. One-dimensional equivalent linear analysis is conducted using PROSHAKE software consisting of multiple soil layers with varying properties, ranging from soft to stiff alluvial deposit formations. The ground motion input consists of a suite of recorded earthquakes embedded in the software. The analysis also includes the effect of ground motion input along with varying soil conditions. The analysis results indicated that the local soil strata properties significantly influenced seismic waves’ amplification and attenuation characteristics. The soft alluvial shallow deposits amplified seismic waves and relatively higher displacements. In contrast, the stiff, deep alluvial deposits showed attenuated high-frequency waves. The analysis also highlighted the significance of seismic-induced ground displacement, primarily linked with selecting ground motion and soil parameters. The results of this research work can be utilised to carry out the seismic hazard assessment of the region and earthquake engineering design, which will contribute to the local community’s safety.
