From the seismic microzonation studies to the site scale: the case of Arpino (Italy)

This paper summarizes the main results of the first level seismic microzonation study performed for Arpino, a small town located in a highly seismic region in Central Italy. Based on these results, further investigations were performed at Arpino Bove test site, selected as representative for one of the microzones prone to ground local amplification. Geophysical and geotechnical surveys were performed at the selected site, including a borehole, a down-hole test, a seismic dilatometer test, noise measurements and several resonant column tests on undisturbed samples. The experimental results were compared and used for 1D ground response analyses to quantify the amplification of seismic ground motion at the site scale.
