This paper analyses site effects that are applied to compute the H/V spectral ratio close to structural lineaments. Aseismic creep and seismic creep have been examined. The lineaments are located in different types of volcanic soil. The aim of the work is to verify the possibility of fault-guided seismic waves within the structures, which behave as a waveguide for trapped waves. The measurements of ambient noise were carried out along profiles crossing the structures, and the standard Nakamura technique was applied to calculate the spectral H/V ratio. It was observed that horizontal components of ground motion were found to be significantly amplified within the shear zone.
