Underground coal mining often causes persistent land subsidence, which would lead to huge threats to infrastructure and safety in the coal area [1, 2]. Traditional levelling and GPS methods are able to produce reliable measurement of ground subsidence [3]. However, these field surveys are time-consuming and cannot provide deformation map with high spatial sampling density. Synthetic aperture ra...

Continuous monitoring of glacial lakes, their parent glaciers and surroundings is crucial because possible outbursts these lakes pose a serious hazard to downstream areas. Ongoing climate change increases the risk this globally due recession leading formation expansion permafrost degradation which impacts stability glaciers, slopes moraines. Here, we demonstrate capability our approach for lake...

Due to the convenient transportation and construction, cities are prone to be situated in areas with flat terrain and unstable sediments, resulting in the concurrence of ground subsidence and urbanization. Here the interaction between geology, anthropogenic processes and ground subsidence geo-hazards were investigated in the Greater Pearl River Delta region of China. Geological evidences and 20...

From 1910 to 2002, the Mines Domaniales de Potasse d’Alsace (MDPA) exploited two potash layers, located at depths greater than 400 m in southern Upper Rhine Graben. This mining activity has caused surface subsidence, investigated here using SAR interferometry (InSAR) and Persistent Scatterer Interferometry (PSI) approach is used follow induced displacements over Alsatian potassic basin. The ima...

Polarimetric SAR interferometry has been widely studied for forest observations. The technique utilizes polarization state difference among local scattering centers of the forest to decompose them. Using the method, we can estimate precise forest parameters. We proposed an alternative method based on the ESPRIT algorithm for the estimation. The method can detect as many as 3 local scatterers wi...

In a recent contribution Ferretti and co-workers (Ferretti, A., Fumagalli, A., Novali, F., Prati, C., Rocca, F., Rucci, A., 2011. A new algorithm for processing interferometric data-stacks: SqueeSAR IEEE Transactions on Geoscience and Remote Sensing 49(9), pp. 3460–3470) have proposed the SqueeSAR method, a way to exploit temporally coherent distributed scatterers in coherent SAR data stacks.
