Outline of Final Research Achievements

We have developed a method to estimate the building structure and building age of each building, which is necessary for estimating earthquake and tsunami damage. At the same time, we have developed time specific human flow data that can be applied to damage assumptions using mobile phone probe data. Using the results of various input seismic and tsunami run-up simulations, the physical and human risks can be estimated in detail by integrating collapses, fires, and tsunamis on a building and human basis nationwide. Based on these various scenarios, a method for extracting scenarios explaining significant damage from sparse modeling has been established. The ability to extract important scenarios from the damage distribution will help us to understand the unique damage factors that occur in each region derived from the time series and input tsunami data.

Academic Significance and Societal Importance of the Research Achievements

地震津波の被害分布から重要シナリオの抽出が可能になることは時系列や入力津波データに由来する地域ごとに起こる固有の被害要因の理解を助長する。地域ごとの被害要因が恣意的でなく科学的に示すことができれば人の流動や震源域 避難行動の違いが被害にもたらす影響またその結果人の行動などがどのような被害軽減をもたらすかの予測が可能 になる。それだけでなく膨大な計算量を要する MAS Multi agent simulation などの 高精度被害推定モデルを効率よく適用する際の入力シナリオの選定においても応用できると考えられ、学術的高い意味を持つと考える。したがって本研究成果は社会的にも大きな意味を持つ。
