We estimate structural damage of Fukuoka City for a scenario earthquake based on the strong ground motions evaluated by a hybrid technique. The 3-D basin structure of Fukuoka City has not been estimated yet, and so we construct the 3-D basin structure below Fukuoka City by using a geological map and a gravity anomaly map, together with S-wave velocity structures at several points inside the basin. Then we use our hybrid simulation technique to estimate broadband strong motions in Fukuoka City for a hypothesized scenario earthquake with four different rupture processes. Based on these ground motions and damage evaluation models of buildings we predict the whole damage of the city. The result shows that we have to prepare for a severe disaster in the center of Fukuoka City, once such an event would occur.
