AB: In this study we present a preliminary evaluation of the tsunami vulnerability of Casablanca area (Morocco) and the expected inundation from a tsunami generated in the North East Atlantic area in the Gulf of Cadiz using a combination of numerical modeling and GIS tools. The study area is the intensively occupied area of the Casablanca Harbor, a location that may be considered as one of the most vulnerable areas to tsunami hazard, along Morocco Atlantic coast, due to its location close to the source of moderate and strong magnitude earthquakes, the extension of low flat areas close to the sea and the existence of dwellings characterized by unstructured constructions. To study vulnerability and inundation we considered geomorphologic and artificial elements as well as the existence of defensive constructions. The inundation zone was divided in for sub-zones according to their height above sea level; the buildings were classed according to: building material, number of floors, conditions of foundation soil. The study area presents a large variety of constructions:1 storey buildings of 2- 2.5 m height, houses and stores of the ancient medina and some modern buildings. The results are presented, using GIS and show a preliminary "picture" of built stock behaviour in case of tsunami for Casablanca. The results clearly demonstrate that the vulnerability to tsunami impact is not uniform within the inundation zone. This work was developed in the framework of NEAREST and TRANSFER projects, EU.
