Figure 10From: Characterization of the response of spring-based relative gravimeters during paroxysmal eruptions at Etna volcanoCharacterization tests of the Scintrex CG-3 M#9310234 gravimeter. Horizontal displacements of the vibrating platform (top) and gravimeter response acquired simultaneously (bottom). In the time indicated by the dotted lines, the platform was moved with horizontal displacements of 25 μm at a frequency of 4 Hz.Back to article page
