“…An exciting advance in satellite observations of volcanoes is the development of radar and optical datasets with spatial resolutions of 3 m pixel −1 or lower with repeat intervals of a week or less (e.g. Planet, WorldView, Pléiades, Radarsat-2, TerraSAR-X, COSMO-SkyMed, Capella, ICEYE) that have allowed investigations of critical, smaller-scale features and their changes over time [Richter et al 2013;Eugenio et al 2014;Aldeghi et al 2019;Waythomas et al 2020;Dai et al 2022;Bemelmans et al 2023]. For example, high spatial resolution Synthetic Aperture Radar (SAR) images from RADARSAT-2 and TerraSAR-X satellites showed changes before an eruption at Merapi, Indonesia and were used along with other data to inform evacuation orders that saved thousands of lives in 2010 [Pallister et al 2013].…”

TerraSAR-X (TSX), TanDEM-X (TDX), and PAZ Synthetic Aperture Radar data have been used at over 120 volcanoes to assess surface characteristics and change over time. We examine previous work, adding additional examples to understand where and when these data are most useful for volcanology. We focus on volcanoes as part of the Committee on Earth Observation Satellites (CEOS) Volcano Demonstrator Project. TSX/TDX/PAZ data provide a valuable means of detecting small surface changes from amplitude images and topographic changes from bistatic TSX/TDX data. For short temporal and perpendicular baselines, TDX/TSX/PAZ can also provide useful deformation data, even in presence of vegetation. No global background mission currently acquires TSX/TDX/PAZ data at volcanoes: 70 % high spatial resolution data, limiting their suitability for studying pre-eruptive unrest. Coordinated targeting by SAR constellations of priority volcanoes would provide data and insights valuable for forecasting eruptions and associated hazards.
