CATANIA, Italy - Mt. Etna, the most active volcano in Europe, erupted twice in less than a week. The first eruption took place on Nov. 16 and the second on Nov. 23.

Lava flows were reportedly shot 700-800 meters in the air. Lightning was also present during the explosion, as well as plumes of gas, smoke and ash.

The ash traveled across the region, coating Giardini Naxos on Sicily with black dust.

It also pushed across the Strait of Messina and into the mainland. Chunks of ash and rock fell from the sky, as big as two centimeters in diameter.

Some rocks and ash can also fall from the sky much like rain, as they are sent into the atmosphere and can collect on clouds to be rained down with later precipitation.
