Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Abstract The limits of detection for earthquake surface deformation in the spatial domain have improved with advances in remote sensing imagery data availability, resolution, and analysis. Sub‐pixel correlation and digital elevation model (DEM) differencing from sub‐meter, earthquake‐spanning satellite optical imagery has enhanced surface rupture ...

Optimal Data Acquisition and Height Retrieval in Repeat-Track Geosynchronous SAR Interferometry
Geosynchronous synthetic aperture radar (GEO SAR) will move in a high orbit of ~36,000 km with a long integration time of hundreds of seconds. It is obviously impacted by orbital perturbations and the Earth’s rotation, which can give rise to un-parallel ...
