Figure 8From: Characterization of the response of spring-based relative gravimeters during paroxysmal eruptions at Etna volcanoResponse of the LaCoste & Romberg D#185 gravimeters horizontally excited. The excitation was performed with signals of 2.0 mg (blue rhombuses), 2.7 (red squares), and 3.5 mg (black triangles) amplitudes (typical amplitude value recorded at BVD station during paroxysmal events), varying in frequency between 2 and 20 Hz.Back to article page
