Numerical and Experimental Seismic Characterization of Byblos Site in Lebanon

A seismic study of Byblos, Lebanon, reveals significant variations in ground motion due to geological and topographic site effects, with potential resonance from soft, shallow layers. Using field surveys that included ambient vibration recordings, surface waves, and 2D seismic arrays, researchers identified multiple resonant frequency peaks indicative of impedance contrasts and lateral subsurface stiffness variations. These findings were validated through a combination of numerical models and experimental observations, marking a critical step in the seismic microzoning of Byblos. The study highlights the influence of fractured rocks and anthropic deposits on seismic ground motions, offering new insights into the area's seismic hazards and contributing to enhanced resilience and sustainability efforts.
