All the buildings in the historical center are scattered among its narrow streets and are located in continuity with each other; the openings are represented by entrance doors and windows, which are generally abundant on the façades. The overall structural typology is masonry, mainly disordered, but a more precise characterisation can be made after inspections or the collection of more accurate information. In following Fig. 4, some details of Santa Lucia district, that represents the zone with an high level of damage, are reported.

3. Expeditious seismic risk method: application of Cosenza historical center In the present paper, seismic risk assessment at territorial scale was conducted adopting the method proposed by Tuscany Region [Bacci et al. (2018, 2019)]. It consists in a statistical approach involving both ISTAT (Italian National Institute of Statistic) data and direct surveys, allowing different levels of details, that are: level 0 ‘ regional scale ’, level 1 ‘ municipal scale ’, level 2 ‘ urban scale ’ . In the specific, for each level, a specific degree of detail is adopted. In level 0, seismic risk assessment is conducted on each considered municipality using ISTAT data; in level 1, the assessment is conducted for each area with homogeneous characteristics, adopting statistics and/or direct survey. In level 2, in addition to what was carried out through level 1, analytical or directly surveyed data can be adopted. Thus, the first part of the work consists of gathering useful information in order to define the basic data regarding exposure risk and vulnerability. In this way, the Risk Class R is determined by means of an index given by the Indicator
