Stromboli is one of the most active volcanoes on Earth and has been erupting almost continuously since 1932. Because it has been active for much of the last 2,000 years and its eruptions are visible for long distances at night, it is known as the "Lighthouse of the Mediterranean". It is among the world's most visited volcanoes.
Mount Etna is Europe's highest and most active volcano. Towering above the city of Catania on the island of Sicily, it has been growing for about 500,000 years and is in the midst of a series of eruptions that began in 2001.
