The World's Most Mysterious Volcano Can Finally Be Explained

A new study says Mount Etna’s frequent eruptions likely come from a rare magma pathway tapping trapped upper-mantle pockets.

That mechanism appears different from a typical hotspot or standard subduction-driven volcanic system.

The finding may explain why Europe’s most active volcano produces so much alkaline magma.

Researchers say the work could improve hazard assessments for nearby Sicilian cities, including Catania and Messina.
