Underground cavities are widely distributed in urban areas and pose a significant risk to buildings and infrastructures. Beyond structural instability issues, cavities can significantly affect seismic wave propagation, modifying the amplitude, frequency content, and duration of ground motion. This study presents an integrated approach to investigate the dynamic response of underground cavities, combining two-dimensional numerical modelling of seismic wave propagation and in situ ambient vibration measurements.

Abstract
Underground cavities are widely distributed in urban areas and pose a significant risk to buildings and infrastructures. Beyond structural instability issues, cavities can significantly affect seismic wave propagation, modifying the amplitude, frequency content, and duration of ground motion. This study presents an integrated approach to investigate the dynamic response of underground cavities, combining two-dimensional numerical modelling of seismic wave propagation and in situ ambient vibration measurements.File in questo prodotto:
