Italy's famous Mount Etna erupted again last Sunday night.
The violent bursts of lava eruptions from Mount Etna are called paroxysms. A 2012 study found that the lava that erupted from Mount Etna each year can fill Chicago's Willis Tower to the brim.
The last major eruption from Mount Etna was seen in 1992. And the first historic Etna eruption took place in 1500 B.C. However, Mount Etna is much older than its first major eruption.
After analyzing 'elements in Etna's rocks', Geologists found that Mount Etna spewed forth lava for the very first time 500,000 years ago.
