Mount Etna is an active volcano on the island of Sicily, Italy, and is one of the largest active volcanoes in Europe. Its height was measured at 3,326 meters in 2018, but the elevation fluctuates due to its intense activity. This volcano is the highest in Italy and the highest mountain outside of the Alps. The diameter of the volcano's base is about 140 kilometers, and its area is approximately 1,190 square kilometers. Among Italy's three active volcanoes, it is the highest, standing more than three times taller than Mount Vesuvius, the second highest.

Mount Etna is highly active and erupts frequently. Although large-scale eruptions can occur, it is not considered a particularly dangerous volcano. Thousands of people live on the volcano's slopes and surrounding areas, utilizing the fertile land for vineyards and orchards.

Mythological legends are also associated with this volcano; it was said to be the place where Typhon was imprisoned and is also cited as the site that caused Noah's Flood.
