Wildfire is a major disturbance in the Arctic tundra and boreal forests, having a significant impact on soil hydrology, carbon cycling, and permafrost dynamics. This study explores the use of the microwave Interferometric Synthetic Aperture Radar (InSAR) technique to map and quantify ground surface subsidence caused by the Anaktuvuk River fire on the North Slope of Alaska. We detected an increa...

Spaceborne SAR Differential interferometry (DInSAR) has been used to monitor some geological disasters such as ground subsidence. This paper applies two Permanent Scatterer InSAR(PS-InSAR) techniques to measure long-term and short-term subsidence in urban area of Shanghai urban. A great number of archieved ERS data are utilized to measure long-term subsidence during 1993-2000 year. A small set ...

The presence of ground subsidence near abandoned coal mine areas can be hazardous to people and property because of its tendency to happen without warning. The prognostication has recently become a serious social problem in Korea, since almost all underground coal mines have been abandoned, and few remain since 1989. However, the effort of scientifically assessment of susceptible ground subside...

Subways have been an important method for relieving traffic pressures in urban areas, but ground subsidence, during construction and operation, can be a serious problem as it may affect the safety of its operation and that of the surrounding buildings. Thus, conducting long-term ground deformation monitoring and modeling for subway networks are essential. Compared with traditional geodetic meth...

a r t i c l e i n f o Keywords: Subsidence Interferometric synthetic aperture radar SBAS time-series Indonesia We use interferometric synthetic aperture radar (InSAR) time-series analysis of ALOS L-band SAR data to resolve land subsidence in western Indonesia with high spatial and temporal resolution. The data reveal significant subsidence in nine areas, including six major cities, at rates up ...

The extraction of ore and minerals by underground mining may induce ground subsidence phenomena. These phenomena produce several types of ground movement like horizontal and vertical displacements, ground curvature and horizontal ground strain at the surface, and associated building damage in urban regions. The influence function is a well-known and efficient method for the prediction of these ...

Estimation of the height of caved and fractured zones above a longwall panel along with the stability conditions of the goaf area are very crucial to determine the abutment stresses, ground subsidence, and face support as well as designing the surrounding gates and intervening pillars. In this work, the height of caving-fracturing zone above the mined panel is considered as the height of destre...

Advanced techniques of multi-temporal InSAR (MT-InSAR) represent a valuable tool in ground subsidence studies allowing remote investigation of the behavior of mass movements in long time intervals by using large datasets of SAR images covering the same area and acquired at different epochs. The settlement in Beijing is very serious, producing adverse environmental impacts. Excessive groundwater...

Ground subsidence monitoring is of paramount importance in relation to the safety and efficiency of underground mining operations. Moreover, in established coal fields in eastern Australia, it has become harder and harder to select underground minesites which can avoid major engineering structures both on the surface and underground (highways, bridges, buildings, abandoned workings of old under...

This paper reports the progress of the ongoing ESA CAT-1 project (ID 1078). Radar interferometry (InSAR) has been used together with GIS (Geographic Information System) technique to monitor ground subsidence due to underground mining in a test site around the Appin township, southwest of Sydney, Australia. Various digital elevation models (DEMs) are assessed using elevation profiles from ground...
