On 16 April 2016, a strong earthquake occurred in Kumamoto, Japan, resulting in 97 landslides in the vicinity of the Aso Volcanological Laboratory. This paper reports the initial photographs and preliminary field investigation of a typical earthquake-triggered landslide near the Aso Volcanological Laboratory. An unmanned aerial vehicle was used to obtain an aerial view of the landslide. On the basis of these photographs, the basic features of the landslide were characterized and the damage caused by the landslide was described. The first-hand information about the earthquake and the landslide presented here should provide the basis for further work.
