| Outline of Final Research Achievements |
In the mountain slope of the disaster area of the Iwate-Miyagi Nairiku earthquake in 2008, researcher extracted the deformed slope where the risk of landslide occurrence is high by the LiDAR data measured at several time periods, and confirmed by field survey. From this survey, it was revealed that progress of deformation of the slope deformed by the 2008 earthquake was observed after the 2011 East Japan great earthquake, but did not progress during the 2015 Kanto Tohoku torrential rain. In addition, the landslide occurred during the 2015 Kanto Tohoku torrential rain was confirmed that the landslide occurred by the 2008 earthquake expanded, and it was suggested that the landslide was occurred due to the influence of spring water.
