Study on Integrating Disaster Simulations in Urban Areas Using a Common City Model and Application to Integrated Earthquake-Tsunami Simulation in Urban Areas.

We develop a method to integrate disaster simulations using a common city model to simulate the response of urban areas under a series of natural hazards. As an application of the developed method, we integrate seismic response analysis of structures and tsunami simulation; a numerical example shows that we can perform a seamless simulation of earthquake and tsunami disasters targeted on a real urban area.
