| Outline of Final Research Achievements |
We developed a couple of computational models to numerically simulate the big picture of fires in tsunami-inundated areas: (1) a physics-based model for the drift and accumulation of tsunami-driven combustible objects released from destroyed buildings, and (2) a statistical model for the number of ignitions in tsunami-inundated areas. The applicability of the models was tested by comparing with the survey results on the burned-out areas and the ignitions in the 2011 Tohoku Earthquake. Moreover, we proposed a method for estimating the fire hazard map in tsunami-inundated areas to know where is more likely to be affected by the fires, in which the accumulating combustible density predicted by the model (1) is used as the hazard indicator. Using the proposed method, we estimated the fire hazard map in Shimoda City on the assumption of tsunamis following the future Nankai Trough earthquake.
