Supporting Information for “Multi-Temporal InSAR, GNSS and Seismic Measurements Revealed the Origin of the 2021 Vulcano Island (Italy) Unrest”

摘要: Introduction We report the results of a parametric study performed on different elastic models used to fit the deformation at Vulcano Island during the October-December 2021 crisis. Data on the deformation are based on a time series of InSAR data from Sentinel-1 (S-1) satellite. Results are reported in Tables S1-S3. Moreover, we report the long-term deformation in the period 30 April-20 September 2022 along the Line-of-Sight of the satellite (Figure S1) and in the East-West and Vertical directions (Figure S2). The comparison between InSAR and data collected at 5 GNSS stations are reported in Figure S4, whereas Figures S5-S9 show the comparison between the three components of the deformation obtained from the best-fitted model evaluated using only InSAR data and the deformation recorded at the 5 GNSS stations.
