CHARACTERISTICS OF THE 2017 FLOOD DISASTER IN NORTHERN KYUSHU AND LEARNED LESSONS

Abstract

 This paper examines the natural disaster in Northern Kyushu in July 2017 caused by the torrential precipitation e.g. 774 mm in 9 hours at Asakura City, Fukuoka Prefecture. Consequently the serious damage resulted from landslides, debris flows and floods, and then a large amount of sediment and driftwood produced encouraged the damage. In this paper, characteristics of the 2017 flood disaster in Northern Kyushu were discussed, and the learned lessons were explained. Since global warming and its attendant influences such as heavy precipitations are expected to continue and to bring condition of non immunity against an increased potential of natural hazard, the better knowledge and ideas on disaster prevention are urgently required.
