Abstract

 The 3-D model of surface deformation was made by aerial photogrammetry and the GNSS surveying was also done in the actual ground, in order to clarify the surface deformation by the 2016 Kumamoto Earthquake. At the verification points, the accuracy of the constructed model was verified. The surface deformation was analyzed by overlaying the 3-D model after the earthquakes on the 3-D model before the earthquakes using GIS. The difference between the DEM before the earthquakes and the DEM after the earthquakes was analyzed in Matoishi and Nagakusa area, Aso-shi. As the result, the vertical surface deformation could be found two-dimensionally and quantitatively. The coordinate values at the center of gully holes and manholes before and after the earthquakes were also measured in Yasunaga area, Mashiki-machi. As the result, the horizontal surface deformation could be found two-dimensionally and quantitatively.
