In order to model ground motions in the realistic and highly heterogeneous basin structure, an unstructured 3D FEM (Finite element Method) is used, which runs efficiently on parallel computers. The simulation results show strong 3D basin effects, especially within the disaster belt at the target sites from KBU to RKI. @inproceedings (kobe98, author = "Y. Hisada and H. Bao and J.
