Abstract
From experiences on massive tsunami damages occurred in Indonesia on 25 October 2010 and Japan on 11 March 2011, we have learned that the development of a tsunami forecast system for the northwestern regions of the Pacific Ocean is required. We applied a multi-functional three-dimensional circulation model, MOHID, for the 2011 Tohoku earthquake tsunami and inundation simulations to determine if the model is appropriate to the forecast system. With three-level nested grids, we carried out tsunami and inundation simulations. In the tsunami simulation, MOHID represented reasonably the tendency of the observed tsunami with respect to tsunami height and arrival time of the maximum height. With the refined grids of 1/150 o and 1/600 o, the simulated inundation area and height were fairly well matched with a satellite image along the Japanese coast.It is found that the increase of horizontal resolution in coastal regions up to 1/600o improved the result of coastal inundation showing the good agreement with the satellite image. Overall, it is concluded that MOHID is appropriately applied to the tsunami and inundation forecast system for the northwestern regions of the Pacific Ocean.
