On July 12, 2026, researchers in Sicily are utilizing drones to predict volcanic eruptions. This innovative approach involves measuring gas emissions from the Grand Crater on the Aeolian island of Vulcano, where intense volcanic activity has been observed.
Drones Enhance Volcanic Monitoring
The use of drones in volcanic monitoring has gained traction over the past 15 years. Marius Schaab, a researcher from the Technical University of Munich, is at the forefront of this initiative. The drones are equipped with advanced gas sensors that allow them to hover safely above hazardous gas plumes, collecting data without exposing researchers to danger.
According to Schaab, the drone operates by sending a laser beam through volcanic gas emissions. This beam reflects off the gas and returns to the sensor, allowing scientists to calculate gas concentrations in real-time. The drone can maneuver around the gas plume, collecting data efficiently and safely.
Understanding Volcanic Gas Emissions
The primary goal of measuring volcanic gases is to enhance understanding of volcanic activity and its impact on the atmosphere. Tjarda Roberts, a collaborator from the National Centre for Scientific Research in Paris, emphasizes the importance of monitoring gas composition changes, which can indicate an impending eruption.
Roberts explains that as lava rises toward the surface, the pressure increases, leading to a higher release of gases. This correlation between gas emissions and volcanic activity is crucial for predicting eruptions and implementing safety measures.
Flexibility and Safety in Volcanic Research
The drones, including one named Tina, are designed for flexibility, allowing researchers to adjust flight paths quickly based on changing conditions. With a weight of only 2.5 kilograms (5.5 pounds), the drone can fly into fumaroles, where gases escape at temperatures between 100–140°C (212–284°F).
As the German team prepares to conduct tests on Mount Etna, another active volcano in Sicily, Roberts notes that drones eliminate the need for researchers to physically enter dangerous areas. This advancement in technology not only enhances safety but also improves the accuracy of volcanic monitoring.
- Drone weight: 2.5 kg (5.5 lbs)
- Flight altitude capability: up to 3,000 meters (9,800 feet)
- Gas measurement temperature range: 100–140°C (212–284°F)
In the coming days, the team will face new challenges as they deploy their drone system on Mount Etna, which recently experienced an eruption. This ongoing research is vital for advancing volcanology and ensuring public safety in volcanic regions.
