Subject of research
1.	Fatality Modeling of Tsunami Disaster Taking into Account Geographical Factors

Research summary
Fatality Modeling of Tsunami Disaster Taking into Account Geographical Factors and Demographic Components Fatalities (Human Casualties) are one of the indexes that society uses to evaluate natural disaster risk. It is important to analyze the damage caused by natural disasters in order to develop models that can predict casualties under different scenarios. To calculate the number of deaths, an equation which can take into account the geographical and social characteristics of a region is needed. A significant amount of research has focused on various types of evacuation from natural disasters, but to date little attention has been given to tsunami evacuation. Currently, in Japan, although there have been a large number of studies of disaster casualty models, the variables used in each model are different and the prediction methods are not standardized. In addition, the models that have been proposed tend either focus on geographical or social factors. However, fatality models that incorporate both geographical factors and social features are still inadequate. Furthermore, social factors including demographic component may differ depending on region. Therefore, we need to understand the influence of variables included in fatality models in order to allow models to take into account regional characteristics.
