At just under 11,000 feet, Etna is Europe's most active volcano. It can burst into action several times each year.
Red-hot, sparkling lava is shooting into the sky in eastern Sicily.
The volcano's latest eruptions began yesterday evening and these can last days and even weeks.

Many young patients have no obvious risks, Weber said, so "we suspect there may be additional factors at play". The American Cancer Society found that now, 3 in 10 rectal cancer diagnoses are in people under the age of 55.
The ongoing eruption with lava fountains and explosions from the volcano's south-eastern crater has so far posed no threat to humans.
Residents in the nearby cities of Catania and Toarmina could see the lava show in the distance. Some even hike in order to get closer to the volcano's mouth, while some are lucky enough to see a volcanic eruption. During that time, the lava flow threatened to swallow a Sicilian village and worldwide aid came as they stemmed the lava tunnel with concrete blocks to stop the flow. A team flew helicopters over Etna and dropped concrete blocks at the edge of the lava tunnel to plug the hole. The volcano's first recorded observation was in 425 B.C. The airport of Catania, about fifty kilometers from the volcano, remained open Tuesday but the authorities were following closely the evolution of the ash cloud.
