In recent years, natural disasters such as a major earthquake and the accompanying big tsunami that cause enormous damage occur. It takes a huge amount of time and cost to restore a social system that suffered greatly every time. In our research team, in the event of a natural disaster that brings about such a serious disaster, we aim to research and develop artificial intelligence technologies that enable to reduce the damage as much as possible, restore the social system once damaged efficiently and effectively, and resume social and economic activities promptly.
