Short summary
This study investigates strong ground motions recorded in Izmir to understand how earthquakes interact with local soil conditions. By comparing observed records with design spectra and simulated motions, we identify differences between expected and actual shaking levels. The findings show that local ground effects can significantly influence seismic response, emphasizing the need for improved hazard assessment and more reliable earthquake-resistant design in urban areas.
