Gravity measurements at volcanoes are performed to understand processes that induce bulk mass/density changes, while ground deformation measurements, are able to constrain the position and the shape of the pressure and dislocation sources. Both techniques pursue the goal to provide a clear contribution to the understanding of magma ascent processes both during the preparatory and final stages leading to the eruptions. Here, we present an electronic spreadsheet developed to enhance the field procedures during combined gravity and GNSS measurements at Mount Etna volcano (Italy). Using the new tool, the combined gravity and GNSS measurements were processed in real time, showing variations along profiles or in selected stations with respect to previous campaigns; great care has been taken in designing the tool for database editing and management.

Abstract
Gravity measurements at volcanoes are performed to understand processes that induce bulk mass/density changes, while ground deformation measurements, are able to constrain the position and the shape of the pressure and dislocation sources. Both techniques pursue the goal to provide a clear contribution to the understanding of magma ascent processes both during the preparatory and final stages leading to the eruptions. Here, we present an electronic spreadsheet developed to enhance the field procedures during combined gravity and GNSS measurements at Mount Etna volcano (Italy). Using the new tool, the combined gravity and GNSS measurements were processed in real time, showing variations along profiles or in selected stations with respect to previous campaigns; great care has been taken in designing the tool for database editing and management.Pubblicazioni consigliate
