Etna May Be a Giant Version of a Tiny Volcano
A half-million-year lava record supports a model in which tectonic flexing squeezes old upper-mantle magma through a persistent leak.
Summary
A half-million-year lava record supports a model in which tectonic flexing squeezes old upper-mantle magma through a persistent leak.
University of Lausanne researchers propose that Mount Etna is fed by magma pockets already present roughly 80 kilometers below Sicily. As the African and Eurasian plates interact, flexing and fractures may push that material upward like liquid from a squeezed sponge. If confirmed, Etna would be a giant analogue of petit-spot volcanoes previously associated with much smaller submarine structures.
