Etna Eruption Grounds Catania Flights, Strands 100,000 and Hits Sicily Tourism by Up to €24 Million

Etna Eruption Closes Catania Airport During Peak Sicilian Summer Travel

A new eruptive phase of Mount Etna that began on 7 August has closed Catania-Fontanarossa Airport at the height of Sicily's summer season, forcing the cancellation, delay or diversion of flights and leaving more than 100,000 passengers scrambling during the Ferragosto weekend.

The National Institute of Geophysics and Volcanology recorded explosive activity at the Voragine crater, at 3,403 metres, along with ash emissions and several lava flows. Ash drifted south and southwest over Belpasso, Adrano, Ragalna and Paternò, and reached as far as Malta and parts of Libya. Lava fronts have descended to about 1,340 metres and are moving toward the uninhabited Valle del Bove, so inhabited areas are not currently threatened.

Air travel is the main casualty. Catania airport has been closed at least through Saturday 15 August because volcanic ash contaminates runways and jet engines; traffic has been redirected mainly to Palermo, Trapani and Comiso. The closure has produced overcrowded buses and trains, scarce rental cars and private transfers between Catania and Palermo reportedly reaching €800.

Although INGV has lowered the alert level from red to orange after a decrease in internal tremors, it continues to watch emissions from Voragine and active lava flows. Authorities have not ruled out further restrictions if ash returns to the airspace.

How a Single Ash Cloud Exposes Catania's Structural Risk and Drains Sicily's Tourism Revenue

Catania's Exposure Is the Weakest Point

Catania-Fontanarossa sits only a few kilometres from Etna, making it highly sensitive to ash plumes even when lava poses no direct danger. This eruption's ash column moved south and southwest, directly toward the airport and nearby towns, which turned a geological event into an aviation shutdown. The Italian government has again questioned the airport's location and revived a decades-old proposal for an alternative facility farther from the volcano, though no such project has ever been built.

The Financial Hit Lands at the Worst Possible Time

Assoesercenti Sicilia estimates the tourism sector's losses at between €12 million and €24 million. That is a meaningful blow because it coincides with Ferragosto, one of the peak weeks for Sicilian hotels, travel agencies, transport companies and related businesses. Unlike a short weather delay, the closure has lasted for days and has affected the entire eastern Sicily entry point, not just a handful of flights.

Ground Transport Shows the Cost of Scarce Alternatives

With flights diverted to Palermo, Trapani and Comiso, demand has overwhelmed land connections. Buses and trains are overcrowded, rental cars are scarce, and some private transfers between Catania and Palermo reached €800. This price surge is a sign of concentrated demand and limited last-minute transport capacity, rather than a fundamental change in Sicilian prices, but it adds immediate costs for tourists and residents.

Lower Alert Does Not Mean Normal Operations

INGV's shift from red to orange reflects reduced internal tremors, but Voragine is still emitting ash and active lava flows remain under watch. The risk for aviation is therefore not over: a renewed increase in ash emissions could shut airspace again. For airlines and tour operators, this creates scheduling uncertainty, while for Sicily's tourism economy it extends the period in which bookings and arrivals may be disrupted.

Next Moves for Travellers, Sicilian Operators and Aviation Planners

For travellers:

• If your trip depends on Catania, confirm rebooking options through the official diversions to Palermo, Trapani and Comiso before committing to a long overland transfer; last-minute private road transfers between Catania and Palermo have been reported at €800.
• Book any train, bus or rental car as early as possible because demand is far above normal while Catania remains closed, and assume plans may change if ash emissions return to the airspace.

For tourism operators and local businesses:

• Use Assoesercenti Sicilia's €12m–€24m impact estimate as a reference point for documenting revenue losses, insurance claims or requests for public support tied to the Catania closure during Ferragosto.
• Plan for residual disruption even after the alert was lowered from red to orange, since INGV is still watching emissions from the Voragine crater and has not ruled out new restrictions.

For aviation and policy planners:

• Treat the reopened debate on an alternative airport farther from Etna as a long-term question; the immediate operational priority is a repeatable ash-contingency plan for Catania that protects runway safety and passenger rebooking during peak season.
