CNN —Flights from Catania airport in Sicily were grounded on Sunday after volcanic ash from an eruption of Mount Etna covered the runways.

In 2010, a volcanic eruption in Iceland sent a huge plume of ash moving across the Atlantic, causing massive disruption to air traffic across Western Europe. In the aftermath of the crisis, international aviation regulators introduced new risk management guidance on flight safety and volcanic ash. Mount Etna is Europe’s most active volcano, and also the highest, at about 3,350 meters (almost 11,000 feet) tall.
