[HTT30-P02] A method for measuring surface rupture displacement by using UAV - Application to the 2014 Kamishiro fault earthquake
Keywords:The 2014 Kamishiro fault earthquake, surface rupture, UAV, SfM-MVS, Ultra-high-resolution DSM
As a result, we were able to create a DSM of a resolution of a few centimeters. The shaded diagram of the DSM indicates the following: 1) Surface rupture has propagated in an intricately bent and branched manner. 2) Small-scale deformation and deformation along several meters of width have taken place. Subsequently, this DSM was compared with the cross-sectional survey and measurements carried out by the auto-level and LiDAR, and it was confirmed that the DSM is characterized by fine topographic changes. However, an error of about 10 cm could have been present depending on the location.
