Variations in the long-term uplift rate due to the Altiplano–Puna magma body observed with Sentinel-1 interferometry

We present new Interferometric Synthetic Aperture Radar (InSAR) observations of surface deformation in the Altiplano–Puna region (South America) where previous studies documented a broad uplift at an average rate of ∼10 mm/yr. We use data from the Sentinel-1 satellite mission to produce high-resolution velocity maps and time series of surface displacements between years 2014–2017. The data reveal that the uplift has slowed down substantially...
