Impulsive supply of volatile-rich magmas in the shallow plumbing system of Mt. Etna volcano [PDF]
, 2018 Magma dynamics at Mt. Etna volcano are frequently recognized as the result of complex crystallization regimes that, at shallow crustal levels, unexpectedly change from H2O -undersaturated to H2O-saturated conditions, due to the impulsive and irregular ...
