Unmanned Aerial Vehicle (UAV) technology is now beginning to transform volcanological disaster mitigation methods. By embedding advanced gas sensors on unmanned devices, scientists can now monitor the concentration of volcanic gas emissions in real-time from a safe distance, minimizing the risk of direct exposure for researchers in danger zones.
A research team from the Technical University of Munich (TUM) has successfully tested a UAV system on Vulcano Island, Italy. During operation, the drone approaches the crater to analyze gases with the help of a laser beam from ground sensors. This method is considered highly effective because the device does not need to come into direct contact with hot, corrosive gases, thereby extending the instrument's durability. In just 15 minutes, the UAV can precisely map gas concentrations within an optimal flight range.
A similar approach has also been applied by the University of Mainz using a drone named "Tina". This 2.5-kilogram device is specially designed to measure complex chemical compositions such as halogens, chlorine, and bromine in areas with extreme temperatures of up to 140 degrees Celsius. The drone's flexible maneuverability allows scientists to map gas fluctuations prior to an eruption, which is a crucial indicator in disaster early warning systems.
The success of the trials on Vulcano Island opens up broader opportunities for applying this technology in more challenging terrains. The research team plans to deploy UAV units to Mount Etna, an active volcano in Sicily, in the near future to validate the technology's performance in more dynamic and real-world environmental conditions.
