Drones test volcanic gas readings to forecast Etna eruptions

Researchers in Sicily are testing drones to measure volcanic gases above Mount Etna's crater, according to the Local Italy. The unmanned aircraft hover near the volcano's edge and pause in front of laser beams positioned at the crater rim, gathering data on gas composition and concentration. The effort represents an attempt to harness drone technology and remote sensing to improve early warning systems for volcanic activity and potentially forecast eruptions before they occur.

The research reflects a broader international effort to understand volcanic behaviour and mitigate risk in regions where active volcanoes pose hazards to populated areas. Mount Etna's repeated eruptions—including the ongoing activity that has disrupted Catania Airport—underscore the stakes of improved forecasting. Early warning systems that can predict eruptions days or weeks in advance could allow authorities to evacuate populations, close airports and ports, and prepare emergency services before ash and lava pose immediate danger.

Sicily sits at the intersection of Mediterranean geology and European climate stress. Etna's volcanic gases—primarily sulphur dioxide and carbon dioxide—interact with the atmosphere and can affect air quality across the region. By measuring gas emissions at the crater, researchers can detect changes in volcanic pressure and magma movement that may signal an imminent eruption. The drone approach offers advantages over traditional ground-based monitoring: it reduces risk to human observers and allows measurement at points difficult or impossible to reach on foot.

The technology is part of a wider global shift toward using artificial intelligence and unmanned systems in volcanology and natural hazard monitoring. Foreign press coverage of volcanic research has increasingly focused on how emerging technologies can improve disaster resilience in vulnerable regions. For Sicily, where tourism, agriculture and settlement are concentrated in areas vulnerable to Etna's activity, advances in forecasting capacity carry direct economic and safety implications.

The Local Italy's report did not specify the timeline for the research programme or the names of the institutions leading the work, but the initiative reflects Sicily's role as a laboratory for Mediterranean science and a frontier for testing climate and geological adaptation strategies. If successful, the drone-based gas measurement system could become a model for monitoring other active volcanoes in Europe and beyond.
