Mount Etna eruption prompts temporary shutdown of Catania airport

"Vulkanausbruch am Ätna schränkt Flugverkehr in Catania ein," the alert bulletin stated, reflecting the sudden shift in aviation conditions.

Italy's national civil aviation authority worked alongside air-traffic control to manage the disruption, issuing notice-to-airmen bulletins warning crews of the ash cloud and reduced visibility. Carriers were instructed to verify engine and airframe contamination checks before resuming transits through the affected sector.

The restriction comes at the height of Sicily's summer travel season, a period during which Catania typically handles tens of thousands of passengers daily. Tourism operators along the eastern coast braced for cancellations of hotel bookings and guided excursions to the volcano's lower slopes.

Impact on passengers and tourism

Local emergency services urged residents in the municipalities bordering the volcano to remain outside restricted zones established by the regional prefecture. Authorities repeated guidance to keep windows closed against ash fallout and to use protective masks outdoors.

The eruption revived memories of earlier episodes in which ash forced the airport to close, including a roughly four-week shutdown in 2023. That disruption illustrated how quickly volcanic plumes can ground flights across the Mediterranean, with knock-on effects reaching mainland Italy and beyond.

Safety guidance for residents

Geophysical monitoring is coordinated by Italy's National Institute of Geophysics and Volcanology, the agency that tracks tremors, ground deformation and gas emissions on Etna. The institute's observatories at Pizzi Deneri and at the other summit stations feed near-real-time data to civil protection authorities.

Scientists at the institute cautioned that Etna's behaviour can evolve rapidly, with strombolian explosions and lava fountaining possible in the hours after a renewed surge. Past paroxysmal episodes, including the events of 2021, produced towering ash columns that drifted across the eastern Mediterranean.

Airlines said they would reassess scheduling once the institute issued an updated assessment of ash concentration and plume height. The airport operator indicated that a full review of the runway and taxiways would be required before reopening to commercial traffic.

Scientific monitoring and next steps

Travel industry analysts noted that prolonged closures can ripple through the wider European network, particularly during summer weekends when seat demand peaks. Carriers are required under European Union aviation safety rules to perform specific inspections before flying through areas of known volcanic contamination.
