Flights were temporarily halted at Catania airport in eastern Sicily on Sunday due to the ongoing volcanic activity of Mount Etna. It marks the third disruption in approximately a month, as eruptions from one of the world's most active volcanoes continue to spew hot ash over runways.

The cloud of ash and smoke forced authorities to impose restrictions on flights throughout the day. The airport authorities eventually lifted the restrictions in the late afternoon but cautioned passengers about possible delays and cancellations due to the earlier disruptions.

Mount Etna, standing at approximately 3,324 meters (around 10,900 feet), is Europe's highest volcano and has been in almost constant activity. In recent weeks, the volcano has experienced intense eruptions, with hot ash and lava being released numerous times since early July.

On Sunday, the National Institute of Geophysics and Volcanology in Italy reported a dramatic "lava fountain" emanating from the volcano, adding to the ongoing volcanic spectacle. Despite its frequent activity, incidents resulting in casualties at the UNESCO World Heritage Site have been rare. However, in 1987, two tourists lost their lives in a sudden explosion near the summit.

The disruptions caused by the volcanic ash have become a recurring challenge for Catania airport, impacting flight operations and causing inconvenience to passengers. Authorities are continuously monitoring the volcanic activity and keeping a close eye on the situation to ensure the safety of air travel in the region.

As Mount Etna remains active, travelers intending to fly to or from Catania are advised to stay updated with the airport's announcements and prepare for possible changes to their travel plans.
