Geophysical models of Mount Etna, Sicily : its structural evolution and implications for slope stability
Mount Etna, Europe's largest active volcano, shows a long history of changing structure and environment, culminating in the modern volcanic edifice with its observed slope instability and region of past collapse (the Valle del Bove). The structure and evolution of the volcano and, more importantly, …

TEMPORAL AND SPATIAL VARIATIONS IN THE GEOCHEMISTRY AND MINERAOLOGY OF THE YOUNGER HISTORIC LAVAS OF MOUNT ETNA, SICILY
… of nine major hawaiite lava field s erupted on Mount Etna during the period 1910-1983 have been extensively sampled. Whole-rock chemical and petrographic data reveal a significant spatial variation within each of the lava fields studied and a uniform temporal variation in the succession of …

Modelling the atmospheric chemistry of volcanic plumes
… adapted WRF-Chem to model passive degassing from Mount Etna, the chemistry of its plume, and its influence on the wider atmosphere. This investigation considers model plumes from the point of emission up to a day’s travel from the vent and is able to reproduce observed phenomena of BrO formation …

Meccanismi di formazione dei tubi di lava
… viscosimeter. Analyzing samples coming from Mount Etna (2002) the following results have been obtained: the fluid is Newtonian and the thermal conductivity is constant in a range of temperature above the liquidus. For lower temperature, the fluid becomes non homogeneous, and the used …

Atmospheric water vapour tomography for DInSAR application and effect of volcanic plume on the microwaves
… variable weather conditions, the estimation of Mount Etna atmospheric anomalies using GPS measurements have noticeable importance to calibrate the SAR interferograms and to establish the effective ground deformation of the volcanic edifice. In this study we presented a method to obtain a 3D …
