Columns of ash disrupted air transportation around the Italian island. Ash from the eruption forced Catania’s Fontanarossa airport to shut down overnight.
The year 2010 was an unusually quiet period for Etna, which last produced a major eruption in 1992.
Etna is in an almost constant state of activity, but is not considered particularly dangerous.
Its slopes are home to farms and vineyards that make use of soil made rich by centuries of regular eruptions.
