The Emilia-Romagna Authority commissioned Eucentre to carry out a regional scale seismic assessment of residential buildings and to update spectrum- and seismic- compatible natural accelerograms for the ground response estimation in the microzonation studies of level III. The results of these studies are available in a specially developed WebGIS platform that is accessible according to two different roles: the technicians of the regional Authority and the practitioners. While the former can benefit from all the platform functionalities, the latter can only download the accelerograms to be used in technical activities such as seismic microzonation. The platform shows on a regional scale map: (i) the seismic hazard, on outcropping bedrock or with ground amplification; (ii) the exposure in terms of number of buildings, dwellings, and population; and (iii) the fragility curves, specifically calibrated for the Emilia-Romagna exposed asset. Furthermore, the platform provides tables and maps with the seismic risk of the building stock calculated for predetermined time windows and return periods, according to the level of the seismic hazard specified by the Italian Building Code. © 2022 The Authors.
