A vulcanologist from the University of Mainz walks through gas during a mission to collect data from gas emissions in the crater of La Fossa, on Vulcano Island, one of the seven islands of the Aeolian Archipelago of Sicily, on July 9, 2026. A team of researchers from Germany are testing a new system for measuring volcanic gases to better anticipate future eruptions. Hovering over the crater of La Fossa, a drone positions itself in front of a laser beam set at the edge of the chasm on Vulcano, off Sicily, and collect data.
