Active faults appeared Kumamoto Earthquake 16, April, 2016 are the first active faults in Japan since practical small drones have been available commercially. We carried a small drone, DJI Phantom4 by air as carry-on baggage from Tokyo. We surveyed the active faults and accompanied small cracks by Phantom4 at Kamijin of Mashiki-Town and Kurokawa of Minami-Aso-Villiage on 1st and 2nd May. Total duration of flight was 108 minutes at an altitude less than 65m.
Diagonal FOV of Phantom4 camera is 94°, image size is 4000×3000 pixels at still mode, and 3840×2160 pixels (4K) at video mode. Spatial resolution is about 1cm at an altitude of 10 m. Although vertical FOV is 72% at video mode compared with at still mode, information is much larger owing to 30 fps, and quality of capture image is good. Bird’s-eye 4K video is very impressive, and useful for research, education and public information.
At September 2016, a part of Civil Aeronautics Low has changed, a new flight rule of Unmanned Aerial Vehicles such as drones put into effect on 10th December 2016. As flight areas are near Kumamoto Airport, there is a possibility we need permission from Kumamoto Airport or MLIT. We will discuss this problem.
