In this work, with the aim of producing shaking-maps which take into account the local amplification phenomena related to litho-stratigrafical condition, a raster map of Vs,30 values at a regional scale is derived for Piedmont, Italy. After the collection and the validation of all data available within the regional databases, a logic procedure in GIS is applied to assign a Vs,30 value to each of the zone with homogeneous seismic behavior already identified in a previous work. The result is a new Vs,30 map for the Piedmont region that allows a better and more reliable reconstruction of ground shaking including a more detailed evaluation of site effects.

Abstract
In this work, with the aim of producing shaking-maps which take into account the local amplification phenomena related to litho-stratigrafical condition, a raster map of Vs,30 values at a regional scale is derived for Piedmont, Italy. After the collection and the validation of all data available within the regional databases, a logic procedure in GIS is applied to assign a Vs,30 value to each of the zone with homogeneous seismic behavior already identified in a previous work. The result is a new Vs,30 map for the Piedmont region that allows a better and more reliable reconstruction of ground shaking including a more detailed evaluation of site effects.
