Dynamic geotechnical characterization of soils subjected to Umbria and Marches earthquake

The Umbria and Marches regions, in central Italy, were severely damaged by the seismic sequence initiated on September 26, 1997. After that event, Local Authorities, GNDT and Servizio Sismico Nazionale (SSN) have promoted and supported some rigorous (Grade 3) microzonation studies in those areas, in order to reduce the seismic risk and to rationalise the land use. A Grade 3 seismic microzonation of the city of Fabriano is under way. This paper presents the results of in situ and laboratory investigations performed in typical deposits of Fabriano area with the main purpose of obtaining representative shear modulus and damping ratio profiles.
