Introduction to Alaska’s Emergency Management Challenges
Alaska’s diverse landscape and topography, featuring towering mountain ranges, vast boreal forests, and immense tundra, pose significant challenges for emergency management during extreme weather events. The state’s unique geography, combined with its remote and rural communities, requires innovative solutions to ensure the safety of residents and first responders. Drones and remote control systems have emerged as critical tools in addressing these challenges, from locating avalanche victims to assessing unstable snow and supporting disaster recovery across vast, remote areas.
The Role of Drones in Emergency Response
Shannon McCarthy, communications director at the state’s transportation department, highlighted the importance of drones in emergency response, particularly during Typhoon Halong, which devastated Alaska’s remote Yukon-Kuskokwim Delta in October. The department used drones and Starlink panels to survey 35 rural communities, collecting 98,000 images and 540 videos, totaling 5 terabytes of data. This information enabled the department to quickly assess the damage and prioritize recovery efforts. McCarthy noted that the department has been honing its skills in disaster response and recovery, leveraging technology to respond more efficiently and effectively.
Funding and Support for Drone-Based Emergency Response
In 2024, the transportation department received a $12.4 million SMART Grant from the federal Department of Transportation to fund initiatives supporting the use of drones for rural infrastructure inspection and emergency response. The department had previously obtained a specialized Federal Aviation Administration waiver for advanced drone testing. This funding and support have enabled the department to expand its use of drones in emergency response, including surveying damage, assessing avalanche risk, and supporting search and rescue missions.
Avalanche Risk and Mitigation
Alaska’s diverse topography also presents a unique threat to infrastructure and rural communities due to the state’s maritime and continental climates. Timothy Glassett, avalanche and artillery program manager for the state DOT, explained that the state experiences various types of avalanches, including loose snow avalanches, glide avalanches, and slab avalanches. The department uses drones for both long-term preventative measures, such as mapping avalanche-prone areas, and for explosive mitigation, triggering small snow slides to prevent dangerous, large-scale natural avalanches. Glassett emphasized that the department’s goal is to mitigate avalanche risk, rather than control nature, and that drones have been a game-changer in emergency response and assessment.
The Future of Avalanche Detection and Mitigation
As Alaska looks to the future of emergency management and avalanche mitigation, the department hopes to adopt new technologies, such as infrasound devices and Doppler radar, to detect ongoing avalanches. Glassett explained that the department aims to integrate closure gates, passive technology on the roadside, to detect an avalanche in motion and send a signal to warning lights or closure gates, closing the road before the public is impacted. The use of drones and other technologies will continue to play a critical role in enhancing avalanche detection and mitigation, ultimately reducing the risk to residents and first responders.
Conclusion
In conclusion, Alaska’s unique landscape and topography present significant challenges for emergency management during extreme weather events. However, the use of drones and remote control systems has emerged as a critical tool in addressing these challenges. With funding and support from the federal government, the state’s transportation department is expanding its use of drones in emergency response, including surveying damage, assessing avalanche risk, and supporting search and rescue missions. As the department looks to the future, it is exploring new technologies to enhance avalanche detection and mitigation, ultimately reducing the risk to residents and first responders.
