In this photo taken on November 16, 2013, Mt. Etna, Europe's most active volcano, spews lava during an eruption as seen from Acireale, near the Sicilian town of Catania, Italy.
Mount Etna, Europe's most active volcano, has erupted again, lighting up the sky over much of eastern Sicily and shooting up a towering column of ash.
The eruption, which began late yesterday and tapered off today morning, didn't endanger any of villages dotting the mountain's slopes, and no evacuation was ordered.
The airport in nearby Catania said two air space sectors above the volcano were closed to flights, but that the airport itself was operating normally, including take-offs and departures.
Etna erupts occasionally. Its last major eruption occurred in 1992.
