Abstract
The following improvements on tsunami damage predicting are examined in order to decrease the tsunami damage: 1) It is checked that the destructive evaluation of buildings of a wide area due to tsunami can be efficiently performed with the numerical model which can calculate a flood of only land area with good accuracy and the gate type Rahmen model. 2) The limit of inundation height that human-beings can stand up to tsunami is obtained using data of a large-scale model experiment. This limit is determined by a slide and changes in the range of 20cm-40cm with sex and height. 3) When the overflow of tsunami occurs on the land area of a steep slope, a strong back-flow will occur. Therefore, a calculating method which can be used for the stable examination against it is also proposed.
