Mount Etna Ash Disrupts Flights At Sicily’s Catania Airport

Mount Etna’s volcanic ash cloud disrupted flights at Sicily’s Catania Airport for a third consecutive day, forcing temporary suspensions and diversions to Palermo and Comiso. The ash was carried southwards by strong winds, creating a potential hazard to aircraft. Operations later resumed after the ash emissions weakened and the aviation alert was lowered, although passengers were advised to confirm their flight status. The disruption highlights the recurring impact of Mount Etna’s volcanic activity on air travel and tourism in Sicily.

VOLCANIC ASH FORCES FLIGHT SUSPENSIONS

Flights at Catania Airport in
Sicily were suspended for a third consecutive day on Monday after volcanic ash from Mount Etna spread into the airspace around the airport.
The disruption affected both arriving and departing flights at Vincenzo Bellini International Airport, one of Italy’s busiest airports and the main aviation hub serving eastern Sicily.
The airport operator, SAC, initially extended the suspension until midnight on Monday because of continued volcanic ash emissions and the closure of affected sections of airspace. Passengers were advised to check with their airlines before travelling to the airport.
The restrictions came during a busy travel period for Sicily, where Catania is a major gateway for tourists visiting the island.

FLIGHTS DIVERTED TO OTHER SICILIAN AIRPORTS

Where possible, some flights were redirected to other airports, including Palermo and Comiso.
The disruption meant that passengers had to deal with cancellations, delays and changes to their travel arrangements, with airlines expected to provide individual updates depending on the status of each flight.
Catania Airport is particularly important to Sicily because of its location near the city of Catania and its role in connecting the eastern part of the island with other parts of Italy and international destinations.
SAC repeatedly urged passengers to confirm their flight status before setting out for the airport.

ASH FROM ETNA’S NORTHEAST CRATER

The disruption was caused by volcanic ash released from Mount Etna's northeastern crater.
Winds carried the ash towards the south, creating a hazard for aircraft operating around Catania.
Volcanic ash is particularly dangerous to aircraft because it can be drawn into jet engines, where it may melt and later solidify, potentially affecting engine performance. Fine ash can also reduce visibility and damage aircraft components.
For this reason, aviation authorities closely monitor ash clouds and can restrict or suspend flights when they threaten flight paths or airports.
Italy's National Institute of Geophysics and Volcanology, known as INGV, has been monitoring Etna's activity and issuing aviation alerts as conditions change.

AIRPORT EVENTUALLY REOPENS

The situation improved later on Monday when the emission of ash from Etna weakened.
The INGV's aviation warning was lowered from red to orange, and Catania Airport returned to full operation, with restrictions on arrivals and departures lifted.
Reuters also reported that the airport reopened after a three-day shutdown, with SAC confirming that the state of alert affecting the airport had ended and normal services had resumed.
However, passengers were still expected to confirm their individual flight arrangements because disruption can continue even after an airport officially reopens.

ETNA HAS REPEATEDLY DISRUPTED AIR TRAVEL

The latest shutdown is part of a wider pattern.
Mount Etna has repeatedly disrupted flights to and from Catania in recent months as volcanic ash has spread across nearby airspace. The problem became particularly noticeable during the summer of 2026, when several periods of volcanic activity affected flights and stranded or delayed large numbers of travellers.
In August, for example, ash from an eruption forced Catania to suspend arriving flights temporarily after the ash cloud moved into the airport's surrounding airspace.
The repeated disruptions have renewed attention on the difficulty of operating a major international airport so close to one of Europe's most active volcanoes.

WHY VOLCANIC ASH IS A SERIOUS AVIATION HAZARD

Unlike ordinary clouds, volcanic ash cannot simply be avoided through normal changes in flight altitude.
The particles can enter aircraft engines and cause serious problems. They can also affect windshields, sensors and other aircraft systems.
Airlines therefore rely on information from volcanologists and aviation authorities to determine whether flights can safely operate.
Italy's aviation and geological authorities have also been working to strengthen cooperation on the monitoring and management of volcanic ash because of its repeated impact on air transport around Etna.

MOUNT ETNA IS EUROPE’S ACTIVE VOLCANIC GIANT

Mount Etna rises to roughly 3,400 metres on Sicily's eastern coast and is one of Europe's tallest active volcanoes.
Its exact height changes over time because repeated eruptions can add or remove material from the mountain.
Etna is also Italy's highest mountain south of the Alps and is known for its frequent periods of volcanic activity.
Unlike volcanoes that remain quiet for long periods, Etna can experience repeated episodes of lava, ash and gas emissions, making continuous monitoring essential.
The volcano has been active for hundreds of thousands of years and is recognised as a

UNESCO World Heritage Site.
A LONG HISTORY OF ETNA AND CATANIA

The relationship between Catania and Etna goes back centuries.
The city sits relatively close to the volcano, meaning that residents and businesses have long lived with the possibility of eruptions and ashfall.
Etna's presence has also shaped Sicily's landscape, agriculture and tourism. The volcano attracts visitors from around the world, while its fertile volcanic soils have helped support farming in surrounding areas.
At the same time, its activity creates risks for communities, roads, businesses and aviation.
Ancient Greek and Roman traditions also associated Etna with the forge of the gods Hephaestus and Vulcan, reflecting the volcano's powerful place in the history and mythology of the region.

TRAVELLERS FACE CONTINUING UNCERTAINTY

Although Catania Airport eventually resumed normal operations, the latest disruption demonstrates how quickly volcanic activity can affect international travel.
For passengers, the impact can extend beyond the period during which an airport is officially closed. Delayed aircraft, cancelled flights, diverted services and crowded replacement flights can continue to affect travel schedules after restrictions are lifted.
For Sicily's tourism industry, repeated disruptions during the holiday season can also create additional challenges for hotels, tour operators, airlines and other businesses that depend heavily on international visitors.

MONITORING WILL CONTINUE

Etna remains under close observation as scientists track changes in volcanic activity and ash emissions.
The latest episode did not result in a prolonged airport shutdown after the ash emissions weakened, but aviation authorities remain prepared to impose restrictions again if volcanic ash returns to the surrounding airspace.
For Catania, the challenge is balancing the needs of one of Sicily's most important transport hubs with the safety requirements created by living and operating so close to an active volcano.
