Autonomous drones measure volcanic gas clouds, offering clearer eruption warning signs
Researchers at the Technical University of Munich have developed an autonomous drone system to measure volcanic gas emissions more accurately. By flying above gas clouds, the drones provide precise data on carbon dioxide and sulfur dioxide ratios, which are key indicators of volcanic activity.
Why it matters
This technology improves the safety and accuracy of volcanic eruption warnings, potentially saving lives by providing better data than ground-based sensors.

Laser beams are sent through escaping gas clouds and reflected by drones. An algorithm uses the reflected signals to generate a map showing gas concentrations, including elevated carbon dioxide levels. The ratio of carbon dioxide to sulfur dioxide is an important indicator of impending eruptions.
