Sicily: Mount Etna ash disrupts Catania flights again

CATANIA, 29 SEPTEMBER 2026 —

Mount Etna’s Ash Cloud Forces Catania Airport Closure, Disrupting Sicily’s Busiest Travel Hub

The disruption shows the growing challenges posed by Etna’s persistent activity, which has repeatedly forced flight cancellations and rerouting this summer, impacting tourism and regional connectivity. Catania Airport’s operator, SAC, confirmed the suspension, advising passengers to verify flight statuses before traveling. The ash, emanating from Etna’s northeast crater and carried southward by wind, has not signaled an imminent explosive eruption, according to the Italian Institute of Geophysics and Volcanology (INGV).

Etna’s Volcanic Activity: A Recurring Threat to Sicily’s Travel Sector

Mount Etna, Europe’s most active volcano and Italy’s highest peak south of the Alps, has been in near-constant low-level activity for centuries. Standing at roughly 3,400 meters (11,100 feet), its height fluctuates with eruptions, sometimes shrinking by meters during high-activity periods. The volcano’s proximity to Catania—located just south of its slopes—has made it a recurring disruptor to air travel, with disruptions reported multiple times this year and in recent summers.

Etna’s eruptions are not new; the volcano’s first recorded activity dates back nearly half a million years, and its significance in mythology is equally enduring. Both Greek and Roman legends placed the forge of Hephaestus (Vulcan) beneath its slopes, cementing its place in cultural history. As a UNESCO World Heritage Site, Etna’s geological dynamism has long fascinated scientists, but its practical impact—particularly on Sicily’s tourism-dependent economy—has grown more pronounced in recent years.

Flight Operations Halted as Ash Cloud Expands

SAC announced the suspension of all flight operations at Catania Airport on Monday, extending restrictions that had already disrupted weekend services. The decision followed the INGV’s assessment that ash from the northeast crater posed a risk to aircraft engines, prompting authorities to halt takeoffs and landings until at least 2200 GMT.

Where possible, arrivals and departures were rerouted to Palermo Airport and Comiso Airport, though the scale of the diversion reflects Catania’s critical role as Sicily’s primary air gateway. The airport, handling millions of passengers annually, serves as a link for both domestic and international travelers, particularly during peak tourist seasons.

Passengers were urged to check real-time updates via SAC’s official channels, as the situation remains fluid. The INGV’s latest bulletin indicated no signs of an imminent explosive eruption, suggesting the current disruption stems from sustained ash emissions rather than a major volcanic event.

Impact on Tourism and Regional Economy

Sicily’s tourism sector, a cornerstone of the island’s economy, has faced repeated setbacks this summer due to Etna’s activity. While the volcano’s eruptions draw scientific and adventure tourism, the associated ash clouds and flight restrictions have frustrated holidaymakers and business travelers alike. Catania, a key entry point for visitors exploring Sicily’s archaeological sites, beaches, and cultural landmarks, has seen cancellations and delays mount in recent weeks.

The diversion of flights to Palermo and Comiso, while functional, adds logistical strain on alternative airports. Palermo, Sicily’s second-largest hub, may struggle to absorb the additional traffic, potentially leading to further delays or capacity constraints. Comiso, a smaller regional airport, lacks the infrastructure to handle large-scale rerouting, leaving travelers with limited options.

Etna’s Geological Behavior and Future Risks

Etna’s activity is characterized by frequent, low-to-moderate eruptions, with ash emissions being the most common disruption to air travel. The INGV monitors the volcano’s seismic and gas output around the clock, but predicting ash plumes with precision remains challenging due to wind patterns and volcanic variability.

While the current ash cloud does not indicate an explosive phase, Etna’s history shows that such periods can escalate rapidly. In past years, the volcano has produced lava fountains, pyroclastic flows, and significant ashfall, forcing temporary evacuations in nearby towns. Catania itself has experienced ashfall during past eruptions, though structural damage has been minimal.

The UNESCO designation highlights Etna’s scientific importance, but it also underscores the need for balanced management—protecting its ecological and cultural value while mitigating economic disruptions. Local authorities and aviation regulators continue to assess whether long-term solutions, such as improved ash-detection systems or alternative flight paths, are feasible.

Outlook: Uncertainty for Travelers and Authorities

As of Monday evening, Catania Airport remains closed, with no immediate timeline for resumption beyond midnight. The INGV will continue to provide updates on Etna’s activity, and SAC has instructed passengers to monitor official announcements for further adjustments.

The situation reflects a broader pattern of seasonal volatility in Sicily’s travel infrastructure, where Etna’s eruptions intersect with peak demand. For now, authorities are prioritizing safety, but the repeated disruptions raise questions about the sustainability of Catania’s role as Sicily’s primary air hub in the face of increasing volcanic interference.

The story ends here, with the last substantive development being the INGV’s ongoing monitoring and SAC’s extended closure notice. No further details on resumption or additional disruptions are provided in the source.
