Abstract After a recharge phase begun in 2007, on May 13, 2008 a new eruption started on Mt. Etna volcano. The final intrusion was very fast, accompanied by a violent seismic swarm and marked ground deformation changes recorded at the permanent tilt and GPS networks. The frame of the eruptive event and the associated phenomena (earthquakes, deformation, lava emission, fracture propagation) generated great concern and fears that the eruptive fractures might propagate dangerously downslope. We modelled the ground deformation ...
