    Description: Taking advantage of a large displacement-release experiment on a twostory reinforced concrete building located in Bagnoli (Naples, Italy), we performed free-field measurements using 3D seismometers, accelerometers, and a 100-m-long vertical array. The ground motion was noticeable: near the building, the acceleration exceeded 5% g. At each measurement point, it was possible to recognize two source terms, due to the tested building and to the reaction structure. The two sources generated different wave trains. High-frequency accelerations propagated as Rayleigh waves, whereas 1–2 Hz waves carrying most of the displacement propagated only as body waves. The experiment lends further support to the hypothesis that buildings are able to modify substantially the free-field ground motion in their proximity: the peak ground acceleration we observed is the 20% of the ground acceleration required to produce a displacement on the building equal to the one imposed during the release test. We recognize, however, the difficulty of a realistic modeling of wave propagation in the topmost layer of a densely urbanized area.

    Description: The job illustrates the activities, the normative and procedural dispositions of the reconstruction in Molise that has been on its way after the 2002 earthquake. The individualized run has been characterized by numerous technical innovations, consequent to the emanation of the new seismic code (OPCM n. 3274/2003). The President of the Region, Delegated Commissioner for the reconstruction after-earthquake 2002, has programmed and coordinated all the activities, using structures of consultation, of address and of technical support. Particularly, the Scientific Technical Committee (CTS) has taken care of the containing directives, the criterions and the general norms for the trial of the reconstruction, emanate through the Ordinance of the Delegated Commissioner n. 13/2003. The Committee for the Microzonation (CMS) has predisposed indications and guidelines, while the CNR Institute for the Technologies of the Construction, in collaboration with the University of Basilicata and Dicat-University of Genoa, has up the guidelines for the investigations of vulnerability and for the interventions on the scholastic buildings, on the churches and on the monumental buildings. Finally, the Delegated Commissioner has ordered that the Local Corporate Bodies were made themselves responsible for the reconstruction realization. In the Campobasso province , with exception of the S.Giuliano diPuglia common, have been compiled about 16.200 preliminary projects (PPS). It is esteemed a general economic requirement of about 1.800 million of Euros for the residential buildings and of about 900 million of Euros for the public works. The reconstruction is in advanced realization and involves the buildings affected by an evacuation measure (Priority A).

    Description: The S1 pecial Issue of the Bulletin of Earthquake Engineering devoted to the new 2 Italian strong motion database ITACA (ITalian ACelerometric Archive) is introduced in this 3 foreword. An overview of the papers published in this issue is presented, providing an idea of 4 the number of problems encountered in the compilation of a database as rich of information 5 as ITACA, of the solutions adopted and of the possible research and practical applications. 6 Most of the contents, though specifically addressed to ITACA and to its accelerograms, can 7 be usefully thought of as an exemplification of approaches and methods that can be used for, 8 and extended to, similar databases in other countries
