Sicily's Mount Etna erupts with majestic cascade of lava

The Voragine crater of Sicily's Mount Etna awoke from a four-year silence with vigorous explosions and incandescent shreds coming out from the top of the volcano. The 3,330-metre-high volcano, Europe's most active, is believed to have the longest documented history of eruptions among all volcanoes — with records dating back to as early as 425 BCE.
