Computer graphic technic has been widely applied to make the visual image of numerical simulation result. In the computer graphics, the view point is generally fixed on the one point with a large height. The virtual reality system with five large screens has been developed in order to make the audience have the presence. In the system, the view point is able to be moved to any point during calculation. The system has been already applied to make the maneuvering simulator, the virtual image of the tsunami attack to harbor and wave transformation. 　In the present paper, the virtual reality of damage to port facilities during 1995 Hyogo-Ken Nanbu Earthquake is developed. The FLIP (Fine element analysis of LIquefaction Program) which is the strain space multiple mechanism model is applied for the numerical simulation. 　The virtual reality system for damage to port facilities is applicable for the oneself who analyses the simulation, the designer and the system which supplies the simple information for the citizens.
