A picture shows a locust killed by sulphuric gas 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.
