Abstract
A simulation model of oil spread due to tsunamis is developed. The equations for the motion of oil are the Navier-Stokes equation and the continuity equation. Since no effects of surface tension is included, the method is only applicable for a short time, in which the inertia and viscous effects dominate. This method is applied to Miyako Bay, on the North Sanriku Coast in Japan. It is assumed that 2000m3 oil spill from tanks due to earthquake. Input tsunami is the same magnitude as Tokachi-oki Tsunami hit in 1968.
