Fukui Prefecture has stepped up its efforts to assist communities severely affected by record-breaking rainfall and subsequent flooding through the innovative deployment of drones, gathering much-needed data for recovery and rebuilding efforts. On September 21, 2024, Zusu City was inundated with torrential rains, with observations noting rainfall rates of 84.5 mm per hour. This meteorological phenomenon created significant turmoil, leaving local authorities scrambling to assess the damage and organize relief efforts.
Promptly responding to the crisis, Fukui Prefecture dispatched staff to coordinate necessary support measures on the same day the disaster struck. Equipped with the latest drone technology—specifically, drones with beyond-visual-line-of-sight (BVLOS) capabilities—local officials recognized the importance of aerial reconnaissance. By September 23, just two days later, the drone team commenced operations, with 11 qualified operators making seven trips to the affected area.
Between September 23 and October 17, these skilled technicians documented the disaster's impact across 72 key locations. Their remarkable efforts culminated in over 101 kilometers of aerial surveys, carefully photographing neighborhoods, access roads, farms, and even water treatment facilities. Each image captured served as more than just raw data; it unlocked the potential for visual assessments and guided strategic recovery initiatives.
Taking advantage of cutting-edge technology, the team utilized advanced digital twin software called TRANCity, which enabled officials to recreate detailed three-dimensional models of the impacted zones. This innovative approach provided local officials from both Fukui Prefecture and Zusu City unrestricted access to the visual proof of landslides and areas where mudslides had overwhelmed homes and roadways. They were able to measure impacted areas virtually, making strategic planning for future recovery significantly more straightforward.
Notably, the deployment of drones not only bolstered the local government's situational awareness but also significantly enhanced communication with isolated communities. With the data gathered, Fukui officials expressed their intent to develop comprehensive recovery plans based on real-world evidence. A local government representative stated, "The data collected is invaluable for our recovery planning and supporting isolated communities," highlighting the positive impact of utilizing drone technology.
Reflecting on the technological advancement brought about by this drone deployment, another official remarked, "Using advanced drone technology, we’re able to assess the damage visually and keep track of recovery efforts." Such statements reveal confidence among officials about the effectiveness of this method compared to traditional survey techniques, especially following unpredictable and destructive weather patterns.
With the flooding crisis serving as both a challenge and opportunity for technological application, Fukui Prefecture's efforts demonstrate significant prowess and foresight. The increase of extreme weather events as per climate models has spurred the need for more precise planning and responsiveness, boosting the utilization of drones as part of disaster response strategies.
Indeed, this case is emblematic of the future of disaster management—a synthesis of technology and strategy aimed at not just recovering from damage, but actively learning and adapting methods to face future challenges head on. The successful deployment and utilization of drone technology during this crisis highlights the promising role it will play moving forward, potentially transforming how recovery efforts are conducted not only across Japan but globally as well.
Looking forward, officials are optimistic about implementing the insights gathered through this aerial reconnaissance, particularly for vulnerable regions often left isolated during disasters. This proactive stance indicates the merging of technological advancements and strategic government planning is becoming more prevalent, paving the way for safer, more informed recovery processes when nature strikes.
