Outline of Final Research Achievements

As a result of reanalysis of the model parameters based on the case of the trench type earthquake for the statistical lateral resistance model which is one of the sliding collapse risk evaluation method of the artificial fill at the earthquake, it was found that it was necessary to change the parameters between the inland type earthquake and the trench type earthquake. So, the optimum parameters of each earthquake type were derived.
In addition, I showed the possibility to easily generate the topography data before artificial fill from US military photographs etc. by SfM / MVS technique.
