Insights into magma and fluid transfer at Mount Etna by a multiparametric approach: A model of the events leading to the 2011 eruptive cycle

A multiparametric analysis of Mount Etna's volcanic activity from 2009 to 2011 revealed a cyclical eruptive behavior characterized by 18 lava fountains from the New Southeast Crater (NSEC) in 2011. The study, which integrated volcanological, geophysical, and geochemical data, identified distinct phases of magma recharge and movement within the volcano's plumbing system. Key findings included accelerated displacement in the eastern flank since April 2009 and renewed summit activity in late 2010, leading to the 2011 eruptive cycle. Geochemical data and ground deformation GPS inversions constrained the depth and area of magma degassing, providing insights into intermediate and shallow storage zones feeding the NSEC activity.
