The area is characterized by high level instrumental seismicity and seismic hazard. The accelerometric network, consisting of one station located at a rock site close to the hill base and of two accelerometers located inside a building at the relief top, recorded the Umbria-Marche aftershocks of 1997 as well as more recent earthquake sequences. In 2001 a temporary seismometric network was deployed at Cerreto di Spoleto village in order to better characterize the ground motion spatial variability along the ridge. The accelerometric network, consisting of one station located at a rock site close to the hill base and of two accelerometers located inside a building at the relief top, recorded the Umbria-Marche aftershocks of 1997 as well as more recent earthquake sequences. Analysis of the accelerometric records pointed out broadband seismic amplification above 1 Hz at the relief top. In 2001 a temporary seismometric network was deployed at Cerreto di Spoleto village in order to better characterize the ground motion spatial variability along the ridge. The seismic station were deployed at the ridge base and along the crest. To this aim we analyzed waveform in the frequency domain through the Horizontal-tovertical spectral ratio method. Except for the trapped waves effect, the results showed no clear evidence of ground motion amplification for the stations located on the crest. This evidence suggests that the seismic amplification observed on the accelerometric records is not related to topographic amplification.
