Sharing Geophysical Data for Seismic Characterization of the Matera (Southern Italy) Urban Area

Summary In the Smart Cities perspective, the digital archiving of all geological, geotechnical, geophysical and engineering data of cities should become a useful tool to plan strategies for seismic risk mitigation in terms of urban planning, seismic retrofitting, and management of post-earthquake crises. The CLARA WebGIS geodatabase, developed and released in the framework of CLARA project (CLoud plAtform and smart underground imaging for natural Risk Assessment) move toward this way; it contains 488 georeferenced and downloadable surveys (such as Downholes, Mechanical Surveys, Salcarenite Sampling Stations, MASW, HVNSR, Seismic Refraction Surveys), the geological and geomorphological maps and map of homogeneous microzones from a seismic response perspective and 215 new single-station seismic ambient noise measurements carried out on urban soils and buildings. CLARA WebGIS is the first publicly available database reporting for the whole urban area the spatial distribution of the soil resonance frequencies and the vibrational frequency of the overlying 4043 buildings, along with the probability of soil-building resonance occurrence. All data are accessible, visualizing, querying and downloadable at this link: https://smartcities-matera-clara.imaa.cnr.it/
