ABSTRACT
The study comes from the necessity to assess the possible consequences of strong earthquakes upon urban areas in order to reduce the risk of material and human lives losses. It is focused on Iași City, Romania, with a population of about 350,000 inhabitants, located at 170 km North-East form Vrancea region, one of the most active seismic areas in Europe. The methodological approach started by making a comprehensive GIS database by using official data and field studies, comprising a series of indicators concerning the buildings (type, age, number of stories, walls area) and their inhabitants as well as local geological features and landslides susceptibility. The official assessments made by present date by taking into consideration the characteristics of buildings identified a number of 369 buildings in Iași City which present different degrees of seismic risk. The fact is that there are many other structures that have not been evaluated, but that could also have a certain degree of seismic vulnerability. The purpose of this study is that, taking into account the already mentioned indicators, to establish correlations between them and to identify spatial clusters of buildings presenting similar vulnerabilities. It is not an engineering assessment, but a pre-assessment that could give an insight on which categories of buildings should be taken into account for future evaluations.

Keywords: seismic vulnerability assessment, buildings parameters, cluster analysis, Iași city
