Investigating Land Subsidence in Japan through Consecutive DInSAR and Law of Material Conservation
Land subsidence causes Earth's surface to sink, flooding coastal areas and damaging infrastructure. It can be monitored using observation wells, global navigation satellite systems (GNSS), and interferometric synthetic aperture radar (InSAR). Given its accuracy and applicability, researchers have recently utilized consecutive differential InSAR to investigate subsidence in the Kanagawa prefecture in Japan. The results were consistent with observation well and GNSS data, indicating its potential for substituting other monitoring techniques.
