Catania airport reopens as Mount Etna ash cloud subsides in Sicily

Resumption of flight operations

Catania International Airport restored flight operations on Tuesday evening after volcanic activity at Mount Etna forced a temporary shutdown of eastern Sicilian airspace. Airport operator SAC announced the reopening of airspace sectors B3 and C1, enabling arrivals and departures to resume ahead of schedule. Flight suspensions were initially set to run until 22:00 local time on Tuesday, but officials lifted the ban once atmospheric conditions cleared. Dozens of scheduled flights, including multiple international routes, had faced cancellations and delays across Monday and Tuesday. SAC issued an advisory instructing all ticketed passengers to verify their flight statuses directly with individual airlines before heading to the terminal.

Volcanic emissions and aviation alert status

Mount Etna, Europe's tallest active volcano at 3,324 metres, began emitting renewed clouds of volcanic ash on Sunday. Italy's National Institute of Geophysics and Volcanology (INGV) through its Catania Etnean Observatory tracked an ash plume that reached up to four kilometres into the sky. The institute issued a red aviation notice, the fourth and highest level on its warning scale, indicating that significant airborne ash posed a hazard to aircraft. Monitoring equipment recorded medium-to-low volcanic tremor, an indicator reflecting the ascent of magma through the volcano's internal conduits. INGV subsequently downgraded the aviation warning from red to orange on Tuesday afternoon as ash output weakened from the summit craters.

Summer disruptions and economic losses

The mid-September closure represents the latest disruption during a turbulent summer travel season across southern Italy. In August, persistent eruptive episodes forced Catania Airport to halt operations for a period lasting between seven and ten days. That previous closure occurred during the height of the summer holiday season, stranding more than 100,000 travellers, including many tourists from Germany and across Europe. A regional association of Sicilian tourism enterprises estimated that the August shutdown generated between 12 million and 24 million euros in economic losses. During both incidents, airlines diverted inbound flights to other regional airports across Sicily, primarily Palermo in the north, Comiso in the south, and Trapani in the west. Ash from the August eruptions was carried across the Mediterranean Sea as far as Malta and Libya.

Location vulnerabilities and tourism footprint

Catania Airport handles approximately 12 million passengers annually, ranking as Italy's fifth-busiest air hub. The airport is located roughly 40 kilometres from Mount Etna, leaving its takeoff and landing corridors directly exposed whenever the volcano erupts. The repeated closures led to calls for Sicilian air infrastructure to be reorganized, including proposals to expand alternative island facilities. Italian Civil Protection Minister Nello Musumeci commented on the geographical challenge facing the airport during the extensive August disruption.

It is not the volcano that is in the wrong place, but the airport.

Despite the recurring operational problems for aviation, Mount Etna remains one of Italy's leading natural attractions, drawing roughly 1.5 million visitors each year to observe its summit craters and lava flows.
