Earthquake risk assessment for Istanbul metropolitan area

The impact of earthquakes in urban centers prone to disastrous earthquakes necessitates the analysis of associ-ated risk for rational formulation of contingency plans and mitigation strategies. In urban centers, the seismic risk is bestquantified and portrayed through the preparation of "Earthquake Damage and Loss Scenarios. " The components of suchscenarios are the assessment of the hazard, inventories and the vulnerabilities of dements at risk. For the development ofthe earthquake risk scenario in Istanbul, two independent approaches, one based on intensities and the second on spectral displacements, are utilized. This paper will present the important features of a comprehensive study, highlight the method-ology, discuss the results and provide insights to future developments.
