Airports play a crucial role in mitigation of seismic-induced disasters, being key elements in rescue operations after an earthquake. Under earthquake loading, various airport components can be damaged because of the ground shaking. It is well known that seismic amplification of ground motion at the surface is strongly influenced by geotechnical properties of the soil deposits. In this paper, the spatial variability of ground amplification is assessed with reference to an international airport in Northern Italy. Homogeneous zones from a seismic geotechnical viewpoint were identified at the airport and, for each zone, stochastic ground response analyses carried out.
