The Tuscany regional government has started a comprehensive project for the evaluation of site effects in about 60 municipalities, located in the territories of Garfagnana and Lunigiana that are under its authority. For this purpose a multidisciplinary task force has been working in order to assess the elastic response spectra taking into account both topographic and stratigraphic amplifications. The main objective is to provide a tool for land use planning, design of new structures and retrofitting of the existing ones. This kind of activity is nowdays completed for Castelnuovo Garfagnana, that is a town of about 6500 inhabitants with a territory of about 28 square Km. The paper mainly focuses on the geological, geophysical and geotechnical investigations concerning the town of Castelnuovo Garfagnana. The results are summarised with special attention to the following aspects: interplay between geological, geophysical and geotechnical investigations; comparison among different geophysical testing methods (Down-Hole, SASW, Seismic refraction); comparison among different laboratory tests (Monotonic and cyclic triaxial tests, resonant column tests, cyclic torsional shear tests); treatment of the experimental results in order to define a model for the subsequent seismic analysis; creation of a database. The main objectives are i) to point out capabilities and limitations of different in situ and laboratory testing methods and ii) to provide enough information on a well-documented case history. The results of seismic analysis at Castelnuovo Garfagnana are reported in a companion paper.

Abstract
The Tuscany regional government has started a comprehensive project for the evaluation of site effects in about 60 municipalities, located in the territories of Garfagnana and Lunigiana that are under its authority. For this purpose a multidisciplinary task force has been working in order to assess the elastic response spectra taking into account both topographic and stratigraphic amplifications. The main objective is to provide a tool for land use planning, design of new structures and retrofitting of the existing ones. This kind of activity is nowdays completed for Castelnuovo Garfagnana, that is a town of about 6500 inhabitants with a territory of about 28 square Km. The paper mainly focuses on the geological, geophysical and geotechnical investigations concerning the town of Castelnuovo Garfagnana. The results are summarised with special attention to the following aspects: interplay between geological, geophysical and geotechnical investigations; comparison among different geophysical testing methods (Down-Hole, SASW, Seismic refraction); comparison among different laboratory tests (Monotonic and cyclic triaxial tests, resonant column tests, cyclic torsional shear tests); treatment of the experimental results in order to define a model for the subsequent seismic analysis; creation of a database. The main objectives are i) to point out capabilities and limitations of different in situ and laboratory testing methods and ii) to provide enough information on a well-documented case history. The results of seismic analysis at Castelnuovo Garfagnana are reported in a companion paper.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
