<講演内容 / Speech content>


In order to build a society that is resilient to natural disasters, the management of infrastructures is necessary. It requires a digital twin concept, i.e., a comprehensive understanding of the situation in a disaster by constructing the same city in cyberspace.
Living with the disaster risk requires preparation against complex disasters. In the case of the Nankai Trough earthquake, it is easy to understand that the earthquake is so strong that it destroys levees over a wide area. That leads to flood disasters because it is impossible to repair all the levees immediately.
We have developed the digital ensemble concept, and we are conducting large-scale numerical simulations for complex disasters for simulating such multimodal disasters for preparation.
