    A hierarchical family of Damage Probability Matrices (DPM) has been derived in this paper from the ones implicitly contained in the EMS-98 Macroseismic Scale for 6 vulnerability classes. To this aim the linguistic definitions provided by the scale, and the associated fuzzy sub-sets of the percentage of buildings, have been completed according to reliable hypotheses. A parametric representation of the corresponding cumulative probability distributions is moreover provided, through a unique parameter: a vulnerability index variable in the range from 0 to 1 and independent of the macroseismic intensity. Finally, an innovative macroseismic approach allowing the vulnerability analysis of building typologies is defined within the European Macroseismic Scale (EMS-98) and qualitatively related to the vulnerability classes. Bayes’ theorem allows the upgrading of the frequencies when further data about the built-environment or specific properties of the buildings are available, allowing the identification of a different behaviours with respect to the one generally considered for the typology. Fuzzy measures of any damage function can be derived, using parametric or nonparametric damage probability matrices. For every result of the seismic analysis, the procedure allows supply to the user of the final uncertainty connected with the aforementioned fuzzy relation between the probability of the damage grade, the macroseismic intensity and the vulnerability classes.

    "Scenario Sismico" is a GIS tool designed and implemented by the authors for the simulation and the representation of real time damage scenarios in Liguria Region. The specific aim of the tool is to suport local Civil Protection departments and government officials for the emergency management, during the first hours after an earthquake event. "Scenario Sismico" can be as well regarded as an useful tool to help formulating general strategies for earthquake mitigation and disaster response planning. Thanks to its user-friendly framework, implemented within ALOV Map/TMJava application, its use does not require any specific GIS expertise. Once the earthquake scenario is set (by specifying the epicentre position, the magnitude and the hypocentral depth) the expected hazard, the physical damage to buildings and the consequences to people, expressed in terms of possible range, are automatically obtained and displayed in terms of thematic maps and databases. The results of the vulnerability and of the exposure analyses for all the Liguria Region are as well provided in terms of maps and databases. This paper is addressed to the presentation and to the description of the software and of the methodological framework at the basis of the "Scenario Sismico" tool. The simulation of an earthquake event is moreover presented, in order to show the effectiveness of the real time damage assessment resulting from "Scenario Sismico" in supporting the emergency management.
