Morocco has faced numerous natural disasters, which have generated significant human and material losses. These damages have shown the necessity to establish a reliable predictive approach for a good management of natural risks. Such approach aims to identify areas on the national territory that are most prone to hazards and assess the level of building vulnerability in these zones. The objective of this study is to assess the seismic and tsunami vulnerability of buildings located in the coastal zone of the city of Agadir in Morocco. In this work, the adopted approach consists of producing GIS maps that define the different types of structures into vulnerability classes in the area studied. Then elaborate vulnerability and fragility models describing the relationship between the probability of potential building damage and seismic intensities in the seismic case or the inundation depth in the tsunami case. The comparison of the seismic and tsunami vulnerability (based on historical tsunamis of the area) shows that all the buildings of this area will incur about the same levels of damage both for seismic and tsunami hazards.
