Mount Etna breaks volcano rules, tapping 80-kilometer-deep magma in a rare fourth category of eruption

Located in Sicily, Mount Etna is Europe's most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from the University of Lausanne (UNIL) shed light on these mechanisms and reveal why Mount Etna may in fact be unique in the world.
