Abstract:
Geophysical prospecting and velocimetric measurements, aiming at the seismic microzoning of the Cerreto di Spoleto area (Perugia, Italy), are presented. Starting from the data obtained by previous geological-geomechanical surveys, seismic-refraction investigations were carried out in order to obtain a dynamic characterisation and a geometrical description of both soil and rock materials. The velocimetric measurements were performed through temporary free-field arrays, recording both ambient noise and small-magnitude seismic events. The analysis of the obtained records is still in progress in order to evaluate the local seismic wave amplification.
