Session 2.3 GNGTS 2023 (a) (b) (c) Fig. 1. a) on the central prominent hill the center of Caprese Michelangelo is show; behind, upon another hill, the Valboncione; b, c) in-situ inspections of the Valboncione historical center conducted by the students In the current work, the vulnerability assessment has been executed adopting the Giovinazzi and Lagomarsino modifiers (2004) based on the EMS-98 scale (Grunthal, 1998). This approach allows a rapid vulnerability quantification of the structures coherent with the low-cost experience of the seminar. No specific information are needed referring to the inner parts of the buildings, while it is possible to execute the vulnerability model through external visual inspection. The vulnerability of each structure is based on their initial class, given by the macro-characteristics of the sample. Later, building by building these macro-indexes are modified in order to obtain values as a function of the structural characteristics of each construction. The vulnerability model has been calibrated on the basis of Italian post-earthquake experience. In this work, the vulnerability indexes together with the relative damage scenarios have been plotted in a GIS environment collecting the different information. The structural features of each building have been gathered into a GIS database and specifically referred to each structural unit. Preliminary, spatial and geometrical information were
