For the preparedness against huge tsunamis, the following were conducted: An investigation of buildings damaged by a huge tsunami caused by the earthquake off the Pacific coast of Tohoku was executed for April 9-15, 2011. Wooden buildings had suffered heavy damage when inundation depths exceeded 1.5m and rein-forced concrete buildings had broken when inundation depths exceeded 5m. Then, the comparison between these damage data and diagrams of Yamamoto et al. (2011) for predicting a building destruction grade was executed, and it turned out that the diagrams could explain the actual building damage well. Finally, it was also shown that the method of applying inundation depths got using a numerical simulation model of Yamamoto et al. to the diagrams predicts the actual damage with sufficient accuracy.
