Structural Survey and Empirical Seismic Vulnerability Assessment of Dwellings in the Historical Centre of Cusco, Peru

A significant portion of Cusco's historic center could see reduced seismic vulnerability through targeted retrofitting interventions. This finding emerges from an empirical study that assessed the seismic risk of dwellings in the area using data collected from an extensive in-situ survey. Researchers adapted a methodology previously used for Italian historic centers to account for Cusco's unique structural typologies. The study, conducted by a team including institutions from Italy and Peru, utilized GIS mapping to visualize building statistics and derive fragility curves. These curves were then employed to evaluate the potential benefits of large-scale retrofitting strategies, offering actionable insights for preserving this culturally significant site.
