Satellite Radar Interferometry is a unique method that gives us a possibility to take measurements of a land subsidence on strictly determined huge areas and with precision state the time range. This method uses the phase signal difference between two SAR satellite images (Synthetic Aperture Radar). Until this time this method was successfully tested on underground coal mining areas in the Uppe...

Abstract: The extraction of underground ore body inevitably causes a large amount of land subsidence. Current reclamation technologies in China mainly focus on stable subsided land. Therefore, a new technology for reclaiming unstable subsiding land is being studied for restoring farmland as much as possible based on a case study in Northern Anhui, China. In consideration of the mining plan, sub...

[1] The dynamic subsidence of the United States east coast is addressed using the discrepancy between regional and global estimates of sea level, elevation of paleoshorelines, and adjoint models of mantle convection that assimilate plate motions and seismic tomography. The positions of Eocene and Miocene paleoshorelines are lower than predicted by global sea levels, suggesting at least 50 m, an...

The paper focuses on the measurement of land subsidence and, more generally, of land deformation phenomena using the differential interferometric SAR (Synthetic Aperture Radar) technique (DInSAR). The paper begins with a concise description of the properties of the differential interferometric phase, which represents the information source for the estimation of the terrain deformation phenomena...

An approach to study the mechanism of mining-induced subsidence, using a combination of phase-stacking and sub-pixel offset-tracking methods, is reported. In this method, land subsidence with a small deformation gradient was calculated using time-series differential interferometric synthetic aperture radar (D-InSAR) data, whereas areas with greater subsidence were calculated by a sub-pixel offs...

Deep hard coal mining activities lead to land subsidence, resulting in infrastructural influences and hydrological changes. In the case of underground mining, a dislocation zone which transforms in the upward direction into flexure of the strata occurs directly above the mined area. A depression is formed on the surface. The shape of this depression depends on the structure of the deposit, mini...

Ground subsidence is one of the key factors damaging transportation facilities, e.g., road networks consisting of highways and railways. In this paper, we propose to apply the persistent scatterer synthetic aperture radar interferometry (PS-InSAR) approach that uses highresolution TerraSAR-X (TSX) imagery to extract the regional scale subsidence rates (i.e., average annual subsidence in mm/year...

introduction vulnerability is a logical effect outcome from risk of living over the hazardous regions as well as the resiliency capacity of people for recovers the damages of hazard events. vulnerability is a complex phenomenon which can effect and observe in from of environmental, political and c-social-economical vulnerability. according to land subsidence hazard affected over the residential...

Subsidence rate in a reclaimed coastal land of Noksan industrial complex, Korea, was measured by C-band SAR differential interferometry (DInSAR). Surface conditions of the reclaimed land are very rough without vegetation with respect to C-band, which makes strong radar returns. However, artificially loaded top soil is subject to change within a short period so that it is difficult to obtain coh...
