Mount Etna, located on the east coast of Sicily, Italy, is known as the most active stratovolcano in the world, with regular, ongoing volcanic activity. As of 8 February 2025, a new eruptive phase of Etna has begun. The volcano spewed out ash clouds and a lava flow extending approximately 3 kilometres. As a result of the volcanic activity, parts of the Catania Airport were closed temporarily, although overall airport operations have remained unaffected. This image, acquired by one of the Copernicus Sentinel-2 satellites on 12 February 2025, shows the lava flow descending from the volcano. The Copernicus Sentinel satellites provide essential data on volcanic activity around the globe, providing authorities and researchers with insights into eruptions and their impacts on human activities.
