Satellite Interferometric Synthetic Aperture Radar (InSAR) measures the Earth's surface deformation at the millimeter-level and has increased the number of volcanoes where deformation has been studied by an order of magnitude (e.g., Biggs et al., 2014;Ebmeier et al., 2018;Poland & Zebker, 2022). InSAR can capture deformation caused by the movement of magma through the Earth's crust (e.g., Reath et al., 2019), by pressure changes within a zone of magma storage (e.g., Chaussard & Amelung, 2012) or overlying hydrothermal system (e.g., Yunjun et al., 2021). In Northern Chile (17.5-27°S), where only 10 of the region's 42 Holocene volcanoes are currently actively monitored using ground-based instrumentation (Aguilera et al., 2022), the systematic displacement measurements possible with InSAR can provide the best record of timings of recent unrest and magmatic activity at Central Andean volcanoes (e.g.,
