The quantification of the devastating effects of earthquakes on buildings can be achieved with the use of earthquake risk assessment. The formulation of strategies to minimise this risk is a complex task which relies on data regarding mainly the hazard, vulnerability and remaining life of the building. In this paper, the case study of Limassol municipality is presented. Initially, the building inventory and categorisation is defined followed by the selection of hazard scenarios and the development of analytical vulnerability curves. In the final part, risk assessment is performed leading to the formulation of retrofitting strategies for long term use.
•Vast majority of existing buildings were designed with no seismic provisions.•Decisions on pre-earthquake retrofitting is a multidisciplinary task.•Optimum retrofit level is determined based on planning horizons.•Casualties influence considerably the optimum retrofit level.•Pre-earthquake retrofit can minimise human fatalities considerably.
