Volcano monitoring using SAR interferometry for the pre-unrest of La Palma and the post-unrest of Santorini
Original language description
This chapter underscores the critical role of volcano monitoring in early warning systems, focusing on deformation analysis using SAR interferometry (InSAR) with Sentinel-1 data. The volcanic islands under study are inhabited throughout the year, but during the summer, their population increases significantly due to tourism. Therefore, it is crucial to have proper monitoring in place to minimize risks. In the first case, we used the Differential InSAR and Small Baseline Subset (SBAS) techniques to analyze deformation before the eruption of 2021 on La Palma. This analysis covered the five months leading up to the eruption. The results revealed that there was a continuous ground uplift in the line-of-sight (LOS) with a maximum deformation of 5 cm during the three weeks preceding the eruption. In the second case, we focused on the post-unrest situation in the Santorini Volcanic Complex, which experienced reactivation events in 2011 and 2012, but no eruption followed. We used the Interferometric Point Target Analysis (IPTA) technique to analyze post-unrest ground deformation from 2015 to 2021. The results show Santorini remained stable. These results highlight the value of InSAR in understanding the response of ground deformation before and after the unrest, contributing to the mitigation of volcanic hazards.
