The role of Interferometric Synthetic Aperture Radar in Detecting, Mapping, Monitoring, and Modelling the Volcanic Activity of Piton de la Fournaise, La Réunion: A Review

Interferometric Synthetic Aperture Radar (InSAR) has provided groundbreaking insights into the volcanic activity of Piton de la Fournaise, La Réunion, revealing the previously suspected mobility of its unsupported eastern flank and offering a powerful tool for detecting eruption-related displacements in remote areas. This review synthesizes key findings from two decades of InSAR data, highlighting its role in mapping subsurface magmatic processes, volcanic edifice architecture, and eruptive behavior despite challenges like dense vegetation and atmospheric interference. While multitemporal approaches and advanced techniques are improving data handling, frequent eruptions remain a hurdle. The study underscores the growing importance of InSAR as an operational tool for monitoring highly active volcanoes globally.
