Context: Mount Etna, Europe’s largest active volcano, erupted spewing ash, smoke, and lava several kilometres high.
About Mount Etna Volcano:
• What It Is? Mount Etna is a stratovolcano and one of the most active volcanoes in the world. It is classified as a Decade Volcano due to its frequent activity and risk to nearby populations.

• History: Etna’s volcanic activity can be traced back over 500,000 years. In recent notable eruptions occurred in 2018, 2021, and now in 2025.

• Features of Etna: Tallest Active Volcano in Europe: Stands at approximately 3,403 metres, making it the highest peak south of the Alps. Expansive Volcanic Structure: Spans an area of 1,190 square kilometres with a basal circumference of 140 km, making it Italy’s largest active volcano. Complex Crater System: Contains five active summit craters and over 300 flank vents, enabling both summit and lateral (flank) eruptions. Strombolian vs Plinian Debate: While some classify it as Strombolian (discrete bursts), others consider it Plinian due to the ash cloud reaching the stratosphere. World Heritage Recognition: Inscribed as a UNESCO World Heritage Site in 2013 for its geological, scientific, and cultural significance.

• Why Do Volcanoes Erupt? Subsurface Magma Pooling: High heat and pressure in Earth’s mantle melt rock into magma. Gas Expansion: Volatiles like CO₂ and SO₂ expand as magma rises, increasing pressure. Surface Fractures: Faults in Earth’s crust let magma escape, triggering eruptions.
